Display formats & i18n

Display formats and localization

Fixes #2 except for the presets. I will tackle that in a different branch, because the presets should be complete rewritten.

It now supports ANY display format for the date, a transform function for the day, month and year displays, a format for the month and year switchers and automagically uses moment's locale.

Locale

Set moment.locale( ... ) to instantly localize the entire picker for a locale, except for the display date. Follow instructions on momentjs.com how to include a locale file.

Display format options

• Use display_format = moment_format for display dates.
  • Accepts any format, such as D [x] MMMM [x] YY.
  • Default is MMMM D, YYYY
  • Consider changing default to the localized variant LL
• Use display_month_format = moment_format for displayed month names (switcher).
  • Accepts MMMM and MM
  • Default is MMMM
• Use display_year_format = moment_format for displayed year names (switcher).
  • Accepts YYYY and YY
  • Default is YYYY

The date parser that accepts now, stringToDate etc. now also parses using the set display_format.

Transformation functions

Right before a day name, month name or year number is displayed in the switchers or the table header, it is ran through a tranformation function

• Use transform_day = function(d){ return d; } to transform the day display right before it's displayed.
  • Defaults to a function that trims the string to a single character
  • No trimming (2 characters) actually looks great.
  • Use moment.weekDaysMin() to match the value with the day.
  • Consider accepting an array of week days etc. to display instead
• Use transform_month for the month switcher
• Use transform_year for the year switcher

The month/year values of the switchers are stored into data variables (because with the transform functions, you could irreversibly transform the string).

@SleeplessByte Made a number of changes due to other issues and requests. If you could confirm this branch is still working I'll take a look and likely merge. Thanks for the PR!!

I'll rebase it :)

[SleeplessByte]

I guess it was still working?

Somewhat. I tweaked it a lot and took out the function actions.. but the idea as a whole was great!
