Add a VS2013 project.  Doesn't actually do anything yet.
Get about as far as I sensibly can with that Windows port without tackling any of the big stuff ...
Cleanup: Catch by reference rather than value where possible (good
practice apparently)
Merge master and twiddle a little bit more

There's ever so far to go to get this Windows port working...
Fix lots of MSVC build errors (but not all)

I should probably re-test this on GCC...
Reduce those VS2013 build errors down to missing WindowWgl only
WIP: Start working on an AFK_WindowWgl
Merge branch 'windows' of github-as-kaiekkrin:KaiEkkrin/afk into windows
Sort out windows branch building on linux
Add an untested WGL implementation of the cl_gl properties
Keyboard input as ASCII characters (and its glx implementation).  Should let me share the keyboard map between wgl and glx implementations.
Complete Windows build.  Doesn't work yet...
Statically link with glew, use shellapi to parse command line.  Getting there...
Sort out a Windows console for AFK's debug messages.

Still doesn't start properly, because bugs in MSVC2013's initializer
list support :-(
AFK now starts on Windows, although nothing shows...
It's starting to work on Windows now (debug build only, very faulty).  Disable shape render to make life easier
Fix Windows keyboard input.
Sort out input in various ways
Fix inversion again in window_glx
Debug shader and suppress crash on quit
