- Remove use of TMRF_DELETEPENDING for deleting timers as this was a bad idea. 
Timers need to be deleted immediately as waiting for them to be deleted resulted in some
processes running out of handles.
Fixes richedit winetest for editor.
- Add flag TMRF_TIFROMWND for timers created from user mode so the thread stored in the
timer object is from the window and not caller.
Fixes an issue where FireFox would not show any of its windows and looked dead.
- When creating and deleting timers, If the window is non null and IDEvent is 0 then the
IDEvent is changed to 1.
- When modifying timer list use UserEnter and Leave instead of a Critical Region only.
