[Duel/FFA] Imprisoned

Thank you for your feedback so far!

• The music problem was simple: It was target_speaker (so in game the music was an ambient), I fixed this problem.
  
• I added mega health in place of mortar, and mortar in place of 50 HP (removed).
  
• I was thinking about changing position of nex gun as suggested, but I couldn't figure what place would be the best so it's still where it was.
  
• I made the middle room trickjump possible without prejumping (although it still requires precision)
  
• I'm not sure about changing ramps into stairs, Silencer. Ramps does not slow you down very much if you know how to use them and give plenty of possibilities for trickjumping.
  
• I addded several details and lamps (Halogene shuld like it!)
  
• I talked to Fisume and Kojn on IRC yesterday so the item placement in next version should be improved.
  
• fixed the god damn map name into iMprsioned
  
• I added trick jump allowing you to skip jumppad!
  

All the following changes are made in v4 version which will be relase in next couple of hours. hold on.
