DatePicker (Calendar) TODOs

[CRImier]

A simple calendar would be easy to make in ZPUI. However, if you think about it, we could really use a calendar-like UI element for picking dates - similar to how there's a PathPicker element, and there's an Utils=>File browser app that's essentially a PathPicker and a few more lines of code. Desired functions:

• [x] Traditional view - month/year on top in a large font, 5 lines for weeks
• [x] Accepting a start value (__init__ argument) - good if it expects same keyword arguments as it returns in the dict
  • [x] Fallback value - today's day/month/year
• [x] Either accepting a return value or executing a callback (like PathPicker does)
• [x] Being able to set date output format as per strftime standards (for either the return value or the callback argument), but still returning a dict by default
• [ ] If you're on first week and press UP, it should go to previous month (same weekday) - same for reverse.

Optional nice-to-haves:

• [x] Show weeks either starting from Sunday instead of Monday (__init__ argument)
• [x] Showing week numbers (__init__ argument)
• [ ] Add a grid of years (on some special key) - to quicker pick from the years (i.e. you need to select your date-of-birth)

Thanks to @derivmug for the work - now there are only TODOs left =)

when you press the KEY_ENTER button it should open up a list of events on said day, and if there are none you should open a create new event menu, or something of the likes

[CRImier]

Yep, that'll be possible once there's a callback addition, I'll work on Calendar app plugins (and implement the event tracking functionality through plugins) after that's added

maybe make it so that when you press KEY_F1 it goes smaller on the calendar size, like we could have Day, Week, month, and maybe a year view, and KEY_F2 would go bigger? e.g. Day > Week

Most of the items are done - thanks to @derivmug !
