Specific date range in CalendarDatePickerDialog

[JozefCeluch]

I added a new feature, where you can set specific dates to mark the range of the CalendarDatePickerDialog by using setDateRange() method. Current version only supports setting the range in years. Behavior of the original setYearRange() method was not changed.

The behavior is the following:

• years and months that are outside of the range are not shown therefore they cannot be selected
• if the range starts/ends somewhere in the middle of a month, the whole month is shown but days that are outside of the range cannot be selected and are displayed in a disabled color
• dates that mark the range are inclusive and can be selected, so it is possible to create a range that has only one day in it

Hi @dodkoC
Thx for this new feature, can you add a usage example in the sample app to show this feature in action ?

Hey @fchauveau
I added the example, let me know if it's ok :)

Hi @dodkoC
Thanks for your work.

I merge this, and i'm going to do some little change to allow to only set min or max limit.
