Machine Gun Jetpack 2

• The console variable to activate the jetpack has been replaced by a command (toggles on input)
• The console variable for toggling the Jetpack Joyride theme has been removed (and subsequently the music itself too)
• The jetpack is finally available in netgames
• You can now change the color of the jetpack and the bullets with jetpackcolor and bulletcolor respectively

Massively special thanks to @DAIMAO, this update wouldn't exist without him.

• Hopefully prevents the rare chance of not gaining any height at some point during the flight.
• "jetpackmusic" is now off by default.

• Music can now be toggled with the console variable "jetpackmusic". It's on by default and it only works if the Jetpack is active.
• The Jetpack now fires a trail of bullets from each chaingun (instead of a single one from the center).
