Wintab32 (Patch 2 of 8) -- Expose more XInput events through the wintab api.

[Robert North]

This set of patches works towards better quality painting in Painter5.
Tested on Painter5 & Photoshop 6.

Note: I'm aware that this doesn't use Jeremy's X11 event timing code.
Patch No. 8 will fix this.

Changelog:
* Don't post messages on Wine message queue, if tablet context flags 
posting are disabled.
* When posting messages on Wine message queue, use message base stored 
in tablet context, not the default message base.
* Ensure that X11 Proximity events put messages onto Wintab message queue.
