[#1062] Add MissileTubes MountPoint Fired state

[oznogon]

Adds a Fired state to missile tubes, equivalent to the Empty state, for triggering scripting events when a missile is fired. The Fired state persists for 0.1 seconds after firing a tube, or after HVLIs exit the Firing state. Also adds TubeFired0... hardware events.

Fixes #1062.

Minimal hardware.ini example:

[hardware]
device = VirtualOutputDevice
channels = 1

[channels]
FiringMissile = 1

[event]
trigger = TubeFired1
target = FiringMissile
runtime = 0.5
value = 1.0
