overlib MDL-19735 Overlib is now included only where it is used

At the same time I have converted the calendar block to use YUI instead of overlib, this introduces one regression in that the panel is shown immediatly but should really have a minimal delay for usability.
This will be fixed once the theme changes for 2.0 have been commited
