UWP Support Overhaul (#819)

* Working build

* Fix build again, stop deleting files

* Hotfix crash, needs investigating

* Remove VS2015.UWP, I cannot update the project

* Lots of UWP work, added keyboard and mouse press support. Still need to finish scroll wheel, mouse position and cursor hiding, plus other stuff that I haven't seen yet.

* Implemented a ton more things, added BaseApp.h to provide common code to UWP apps.

* Remove constant window dimensions

* Enable and Disable cursor support.

* Actually use mouse delta

* Gamepad Support

* Cleaning and small tweaks

* Restore original example.

* Update comment

* Use 'Messages' to handle the cursor functions so code is more portable.

* Comment

* Comment unused message fields and use vector for mouse pos instead.

* Move messages to utils.h and use messages for everything. No more plat-specific code in raylib.h
