consistency in JSON and XML property name casing

There currently is no consistency in the casing of property names in our JSON resources and JSON output. The project was built piecemeal, but it's perhaps time to clean it up with a consistent use of casing so that developers will know what to expect.

While Google recommends to use camelCase for property names in JSON APIs (see the Google JSON style guide), most APIs today are using snake_case:

So we should refactor the codebase to use the most common format being adopted, which in this case is snake_case.

As for XML element names, there again isn't really a consensus on the casing:

W3C seems to prefer using lowercase.
.NET seems to prefer PascalCase
NIEM (National Information Exchange Model) recommends PascalCase for elements and camelCase for attributes
Google recommends camelCase
the UN/CEFACT XML Naming and Design Rules Technical Specification Version 3.0 (page 23) recommends PascalCase for elements and types and camelCase for attributes

Considering that the majority of the recommendations is to use PascalCase for elements and types, and camelCase for attributes, we will adopt this convention for XML.

Currently refactoring the codebase in the temporary v9 branch, which once stable enough will be pulled into the dev branch. v9 has nothing to do with a version 9, it's simply an escamotage since the only possible version names useful for testing purposes (the way the LitCal server is set up) are either dev or v[3-9]. Not wanting to mess with dev yet for this feature branch I simply named it v9 temporarily, but it will be pulled into dev which will become v4 when proven stable.

The situation currently much better on the v9 branch, a lot of refactoring has been done so far.

Here is some more that still needs to be done:

[x] /calendars endpoint (https://litcal.johnromanodorazio.com/api/v9/calendars):
- [ ] refactor the litcal_metadata property to litcal_calendars
- [x] refactor the national_calendars sub-property to a true collection with properties such as nation : ITALY rather than using the country as a property name, and the collection of dioceses under it's own property dioceses alongside nation; we could even add a nation_lcl property with the translation of the name of the nation into the most spoken language of that nation
  - [x] merge the national_calendars_metadata property into the national_calendars property to simplify our output, this way we avoid duplicating the dioceses too
- [x] refactor the diocesan_calendars sub-property to a true collection with properties such as diocese: DIOCESIDIROMA rather than using the name of the diocese as a property name. What should happen with the current property diocese, which contains the nicely formatted name of the diocese? Perhaps rename it to diocese_nice or diocese_pretty or diocese_name or something like that?
- [x] refactor the diocesan_groups sub-property to diocese_groups which perhaps is a bit more clear that we are referring to a group of dioceses and not to groups of people within a diocese? And here again we should avoid the name of the diocesan group as a property and instead create a collection, where each result will have properties such as group and dioceses
- [x] is it necessary to refactor the wider_regions sub-property to a collection of objects, or can we just leave it as is, a simple collection? REFACTORED
- [x] perhaps we can remove roman_missals from this endpoint seeing we have created a specific missals endpoint?

To that end, here are all the places where the property litcal_metadata is used in this repo (v9 branch at least):

[ ] calendar endpoint (https://litcal.johnromanodorazio.com/api/v9/calendar):
- [x] if we want to be consistent about an underscore for every word in our snake case, then perhaps we need to refactor:
  - corpuschristi => corpus_christi
  - returntype => return_type
  - calendartype => calendar_type
  - eternalhighpriest => eternal_high_priest
  - datetime => date_time
  - eventidx => event_idx
- [ ] perhaps litcal should become litcal_calendar to be more consistent with the naming style of the other endpoints?
- [x] in any case litcal needs to be refactored so that it is a true collection of lit_event objects with a property event_key that can identify the liturgical event (currently, the property name of the event object)
- [x] similarly solemnities and feasts_memorials (under metadata) should be refactored as true collections where instead of using the event_key as the property name, we would create an actual event_key property in each result in the collection
- [ ] perhaps request_headers can be considered an exception? can we just leave them as? or should we refactor this into a collection where each result will have properties name and value? well, maybe we should...

This could be tricky to implement, and will require quite a bit of refactoring.

Here are all the places in the v9 repo where ->litcal shows up:

[x] The propriumdetempore resource needs to be refactored as a collection, where instead of using the event_keys as property names we would create an event_key property for each result in the collection.
