Changed "big_poof" to simply "poof".
The word "big" will only appear if there are small, medium and large versions of the explosion.
Otherwise, it will just be "explosion" and "small_explosion".
Easier-to-understand names for explosions, which can be used in the future. Can phase out old names/numbers slowly.
Also included some explosions from the C&C Content which were not in use and did not have names.
- Expose the beam duration to the projectileinfo
- Play an explosion animation at the target
- Beam tracks moving targets
- Disable player beam color in C&C
