CMS Overhaul

[Ardnived]

An overhaul of the whole admin interface, and namespacing of the CMS code.

I realised that there are a lot of Many-to-Many relationships between the different models, and could do with another way of being represented. Since this is a massive PR, and I thought I'd post some pictures just to help you get your head around what's going on.

Essentially now, every record can be viewing in the CMS and will show a series of tabs for all the other records that are related to it, plus an overview tab called "Info" Eg. A country will show...

• General Info about the country, including some statistics about registration trends
• Regions within the country like provinces or cross-border areas like NYC, and allows you to add new regions
• Managers for that country, where you can also add or remove managers
• All Venues within that country, but new venues should be added on the Province page.
• All Events within that country, but new events should be added on a venue page.

An event will show...

• General Info about the country, including some statistics about registration trends
• Images that have been uploaded for this event
• Managers for that event, including any inherited managers
• A list of all Registrations for this event, ordered by most recent.

And here are a few other samples:

WORLDWIDE DATA PAGE

VENUE PAGE

MANAGER PAGE

A non-administrator will only have access to their Manager page, and through that, access to the pages of any Regions/Venues/Events that they are allowed to manage themselves.

This PR is now ready to be reviewed and merged, there is one issue that I uncovered while doing this, but I've made a separate issue #20, instead of resolving it in this PR.
