Added a few goodies for custom games; this is basically a completed port.

- Added some new Halo MCC Revised tag fixes by Aerocatia ( hud_ammo_outlines update )
- removed mp_needler; moved the fiesta / modified needler from weapon index 3 to index 15
- moved Music Gun to weapon index 3 (now available from Fiesta/Random, affected by more weapon sets; it had a shotgun blast like secondary trigger which made it fit with short range weapons anyway)
- created copies of the Energy Sword and Mine Launcher, put them in weapon indexes 10 & 11, made them map default starting and secondary (these weapons are available in all weapon sets, unlike the map defaults from the previous patch)
- changed the equip/ready sounds of the Energy Sword, Mine Launcher and Music Gun (got tired of the Plasma Rifle ready sound used by 3 different weapons) to Digsite ones. Energy Sword melee given Digsite melee sound. Mine Launcher ammo pickup sound changed to Rocket Launcher ammo.
- finally I changed the cyborg.model_animations to allow you to enter passenger seats of all vehicles when unarmed (currently using flamethrower animations)

Update to work with Current Version of MCC; also
- Stun damage effects from the Ghost and Banshee projectiles have been removed. Special Bus' secondary fire uses damage effect tags from the Ghost again.

Ghost and Banshee projectile damage effect tags in MCC cause stun however they did not in the original Pipe Dream. The changes were necessary because the Shadow (Spectre / stingray like) vehicle was balanced in the original Pipe Dream to be the only vehicle with projectiles that could stun

Botched update (didn't work with the current version of MCC).

- removed the ending 7 seconds of silence from the Mech's music
- Updated the UI of the Fiesta Needler
- bunch of changes to match Pipe Dream's original globals
- updated the Special Bus, no longer uses the actual ghost's projectiles (changed to match what was in the original Pipe Dream; basically Special Bus projectiles no longer stun) and the Special Bus' physics match the original (0.5 gravity scale)
- added new Halo CE Revised tag fixes (Sniper ui/hud/bitmaps) by Aerocatia / Vaporeon
