Fix compilation of hwengine on ffmpeg 0.7.13. But frontend does not compiles.

Hedgeroid: Major overhaul of the network connection code. Now it is threaded and errors are handled properly.

Score AI resurrection as a kill. These values will not be the same as the in-game scoring, since in-game scoring doesn't count friendlies.

fix for older ffmpeg (0.7.13)

Hedgeroid: Misguided attempts at getting the connection lifecycle right. Committing this because it basically runs this way, so i might want to revert to it later :)

remaining files for the Danish translation

When there are videos that are being encoded and user tries to quit display dialog with warning.

Hedgeroid: Reworked player and room lists, added menus, added playername query Still work in progress...

- Check ready status only after deleting player's teams (should fix the bug when you're unable to start game) - Send LEFT message after deletion of player's teams (no idea if this breaks anything, but this is more accurate behavior)

When compiling with sdl2 use it instead of glut for creating hidden window (as suggested by koda). This is not tested but it should work.

Hedgeroid: More work on the lobby activity

Limit firepunch/whip drowning checks to max AI, bat to top 2 levels.

merge

Hedgeroid: Lobby activity improvements

unbreak grayscale

Hedgeroid: Modified detection of assets on SD card (should be more reliable)

It is global var

Hedgeroid: Got the roomlist working... more or less.

Fix crash when hedgehog dies while switching from it

Re-Added the commandline client, but it's not compilable agains the latest frontlib at the moment.

free up power for use by script

frontlib: - Removed automatic roomlist handling, since the server doesn't inform of every change after all - Added flib_netconn_get_playername - Added a callback mechanism for logging

Allow script to set number of ammo in a crate. untested.

frontlib: Fix onRoomUpdateCb receiving a null pointer
