DatePicker feature requests

[harmendv]

Add support for a specific enabled range(s) where the user can pick from. Maybe instead of years from date to date or better, an array with multiple ranges. Maybe From A-B then from D-F and G-J etc.
Add support for date validation (enable/disable specific dates). Must be computed and must expose the start/end range (f.e. if user can only select one week, all other dates above this week must be disabled dynamically)

Clicking onClickPrevFirstMonth causes error when own lowest point. (same as onClickNextSecondMonth on highest point)
