MissionController improved
Updated data submodule
Added function endmission()

Works only with MissionFile version=3
Created for MissionController, but works on any bot
- 1st parameter:
* ResultWin - win mission
* ResultLost - lost mission
* ResultLostQuick - lost mission (Me died)
- 2nd parameter: win/lost delay, like in mission file. Doesn't work for ResultLostQuick.
Please don't use for cheating =)
Minor refactoring
Removed sound081.wav

It wasn't used in Colobot and caused errors because we removed it from data package.
Removed some warnings

+ fix for previous commit
Made colobot.ini & savegame dir location depended on build type

For Debug, it's current dir
For Release it's like it was before
Made on @CoLoRaptor's request :)
Saving information to profile (#154)
Increased maximum font size
Functions playmusic(filename, repeat) and stopmusic()

for MissionController
Parameter repeat can be 0 or 1
Updated Main Mnu music

For now only code - we need to wait for PiXeL to give us new music :)
Added CacheAudio to level files
Small changes to looping main menu music
Improved music cache
Updated data submodule
Added button for Destroyer

Issue #142
Fixed Destroyer button

* Commands were executed for all Destroyers on map
* Button can't be clicked when Destroyer is working
Improved MissionController movement a little bit
