Title: Core/Calendar: Completely rewrite and fix most of the calendar system

There are still some issues that needs to be fixed, for more info see CalendarHandler.cpp TODO part.
Some unblizzlike behaviour possible, we don't have a lot of sniffs.
Big thanks to Warpten, he joined my project and helped a lot.

IMPORTANT NOTE: Read / append packed time functions in ByteBuffer.h are not correct, they need to be fixed in order to have event times accurate
