	  not allocated it until needed. Saves alot on memory usage
	  when using many widgets.

	  different loading policies for the items, and customizable
	  WMenuItem look (through OO inheritance).

	  classes in the examples.

16-08-2006:

	  and other things in WEnvironment

	* rewrote WFileUpload -- works well but looks ugly (most of the time)
	* fixed some memory-leaks indicated by valgrind

	* added side specific margin and padding, moved padding to
	  WContainerWidget
	* More documented members in WWidget
	* release 1.0.11

21-12-2005:
	* added WFont, and use in the wt-homepage example (for the navigation
	  menu)
	* discovered, but not fixed, the reason why going back to the Wt page
	  does not work: when going backward, the page replays the same stuff
	  as if it was unloaded. So, we probably want our first keep-alive
	  message to be 'load', which should find out which things were
	  stubbed, and retransmit these -- are easier just trigger a reload

	  instances (as suggested by Graydon Hoare).
	* quit the application nicely on timeout by exiting the eventloop
	  (as suggested by Wim Dumon).
	* release 1.0.9
