simple artificial intelligence base class; teams remember number
* simple ai which can be started by ai cheat which simply skips the move
* teams now know the team number
Let us make simple AIs in our image, after our likeness.
And let them have dominion over the penguins of the sea and over the unicorns of the land and of every item that creeps on the earth.
* SimpleAI choosing a random weapon (1-4), aiming (straight) at the nearest enemy.
* ais cheat
ctrl+D accident before last commit
first code for moving associating ai with team
AIType enum missing
take 2nd closest enemy when terrain is on the way to 1st one
made ai a finite state machine
Merge branch 'ai' into aiinteam

Conflicts:
	src/de/hhu/propra/team61/MapWindow.java
integrated ai into round mechanism
add ai for every team for now
Merge branch 'aiinteam' into ai
make pause work during ai turn
ai uses medipacks and "appropriate" weapon
missing return added (user input during ai turn not ignored)
ai does not hurt friends, uses digiwise
* skip if all alternatives cause hits near friends
* use digiwise randomly when having enough life, or being last figure of team
* use medipack when being last figure of team (regardless of own hp)
weapon choice depends on enemy hp, better use of digiwise
(not used when already digitated)
more intelligent item usage
fixed error in crosshair offset calculation (radians …)
go to next enemy when no-one can be hit
speed up ai movement
continious calculation of movement
