Removed the impulse2/+forward2 etc commands.
Added +p2, -p2, p2 commands as a prefixed command instead. don't use + or - on them (so '+p2 forward' to move player 2 forward), this permits a simple generic way to send commands to a single player from an input device.
rawinput mice will submit commands/movements based upon idx%maxsplits, they will correctly submit mouse clicks, which will be mapped through the +p2/+p3 commands as appropriate, so each mouse is purely for a single player.
Fixed player model visibility in splitscreen mode.
Ignoring allow_splitscreen for the local player, cl_splitscreen is technically now the only enabler (though you will need to configure rawinput or binds).
Added support for { texturename prefixes.

In this version: replacement GL backend. Replacement D3D backend sharing code with GL. Lots of code reorganisation.
