BDate: added time_t constructor.

* This class is pretty much useless as it is.

Add setters to BDate and BCalendarView

* BDate setters don't perform any validation, use with caution.
* BCalendarView setters do perform validation checks, and will adjust
the day so it fits the requested month or year.
* Add tests for the BCalendarView setters.

Style fixes to Support Kit files

BDateTime: Time_T functions return or take a time_t

* They used an unsigned int, which led to overflows when trying to set
them to a time before January 1st, 1970 (local time)
* Some things use January 1st, 1970, GMT (or UTC) as a reference point.
In my timezone this leads to such a negative date. An example is cookie
expiration dates which are set to this date to expire them immediately.
Spotted by Opera testsuite.
* This makes the method unuseable for dates after 2036 (signed 32-bit
time_t will overflow then. This gives us just 33 years to switch to a
64-bit time_t. In te meantime, please try using other methods to set the
date and time for BDateTime objects if you need to go this far.

Moved Easter holidays methods to a Holiday class, an hopefully better place.

* changed some methods to static as that's what they are in the end.
* added some methods to find out easter sunday, ascension and pentecost days.

* Added copy constructors.
* Let the AddHours(), Add*() return itself, so that they can be chained.
* Made the previous *Name() methods static and added non-static versions that
take the day/month of the object.
* Make BDateTime::Date/Time() return references (const or non-const).
* Fixed the BDateTime comparison operators.

* Indentation update in DateTime.h
* Extended BTime, BDate and BDateTime with archiving functionality.
* Adjusted code which uses these classes, since including DateTime.h
already imports the classes from the BPrivate namespace.
* Moved DateTime.h into Support Kit. It is still in the BPrivate namespace,
as I am uncertain what to do with time_type and diff_type. I'd favor
moving the constants into the classes itself. Possibly removing the B_
prefix from them. Feedback welcome.
