* WINDOWS: Touch server integrated into module
The touch server functionality has been integrated into the touch module
which is enabled by-default when the touch module is used on a windows
build.
The touch-hook checks for a connected digitizer (pen or touchscreen, but
I haven't tested pen)
This commit should also fix two potential low-risk race conditions in
the tuioear.cpp file.
* Added comment regarding which window we use
* Added copyright notice on the win32_touch files
Also changed from #pragma to #ifndef
* Fixes based on review
- Added anonymous namespace
- Put win32hook in openspace namespace
- Fixed indentations and linebreaks
- Fixed an issue regarding global state deinitialization
