Jetpack power limit patch

[mdoison]

Jet-camp is a main problem in Tremulous rules : many players fly at the top of the level, where aliens can't go, and snipe with a lasgun or a mass driver, or more stupidly with a blaster.

At server side, jetpack power limit patch make two things:

• Add a power to jetpack: When you use your jetpack, your power decrease. If you have no power, jetpack stop to work. If your jetpack is off and the reactor is up, your power increase speedly.
• Make jetpack usable even if reactor is down : you can use your jetpack without reactor, but you can't recover your power without this reactor. It's more realistic, and make reactor moves are more easy.

At client side, jetpack power limit patch add the reactor powerbar in GUI when you have reactor in your inventory.
