finished semibot and environments

semibot is the final bot, to start it and to get it back running after
it found a block in a room (a route should be drawn), give any
command/chat to itself/all to get it back running. Commands can be given
in the chat window or with right click on the map.

There are 12 different environments, all with 4 casualties. They are in
Maps/4cas.

It might not run on other computers since the foldernames of the files
are not correct, the .jar server is depending on foldernames and I can't
put the .jar server in the USAR folder (the server seems to be depending
on other files in the goal directory).
