BSD: Add support (#140)

* BSD: Add support

* BSD: other fixes

There is still a bug when vgui haven't got text, maybe because of resources.

Also there is bug where when trying to start new game caption names shows wrong.

* BSD: Debugging

* BSD: modify preprocessor and fix windows

* BSD: Remove debugging and fix labels in gameui

* BSD: Remove disabling some DX9 commands

* BSD: Remove -g flag
