BUGS
- Change SDL cursor to resemble the OS cursor (John)
- Sensitivity is off (SDL related? Or can I try and replicate the original behaviour?) (John)
- The view jumps after the input has been released and recaptured (John) (not for me on OS X)
- "maps" and "mods" commands don't display anything (John) (there's no support in SDL or stdlib for this)
- Paste doesn't work (needs to be implemented in platform.h) (John)
- Keybindings are not loaded correctly upon first start? (spirit)
- Log everything to the shell as well as to the console (spirit)

OTHER STUFF
- Implement TCP networking.
- Clean up in vidsdl: remove windowed and determine window state from modestate ?
- Fix Sys_Error behaviour (what is quake double error?)
- Open Console with Circomflex or Shift-Escape
