Incorporate multi-screen, multi-touch support from previous projects

[benjaminbojko]

Things to do:

• [x] Combine code from TouchWin8 and MultiNativeTouchDriver into a single NativeMultiScreenTouchDriver
• [x] Add code from MultiNativeTouchDriver and TouchWin8 and
  • [ ] Move the touch script to src/bluecadet/touch/drivers
  • [ ] Namespace it under bluecadet::touch::drivers
  • [ ] Add a disclaimer/comment to both the .h and .cpp with a link to where the code came from and attribution to the author
• [ ] Add AppBase logic to detect the number of displays and automatically choose the correct native touch driver if native touch is enabled (and TUIO isn't)
