Build: Enable SSL in mingw by linking against WinSSL

The mingw builds aren't submitting telemetry because the curl library
they are linked against is configured to use openSSL and openSSL looks
for the certificates in the users home folder. This keeps it from
contacting web services because it can't communicate over SSL.

This commit adds a download in mingw builds that will download a
precompiled curl for mingw linked against winssl and sspi.

travis_OSX: build with system curl

PICA: implemented geometry shader

interpolate: Interpolate on a frame-by-frame basis

SwRasterizer/Lighting: implement bump mapping

Refactor touch input into a TouchDevice

There is currently no stage tracking, a client is considered "Connected" when it receives the EAPoL Logoff packet from the server, this is not yet implemented.

Services/UDS: Store the received beacon frames until RecvBeaconBroadcastData is called, up to 15 beacons at the same time, removing any older beacon frames when the limit is exceeded.
