Rewrites gun.dm. Reorganizes the firing procedure into logical procs and cleans up some unnecessary variables or demotes them to the subtypes that actually care. Energy weapons that create their own projectiles no longer care about in_chamber. Launcher support is much more natural now.
Cleans up duplicated cyborg energy weapon power supply code. Adds support for energy weapons to recharge from external power sources, unifying cyborg and hardsuit mounted weapons. Incorporates the cyborg taser recharging mechanism. Cleans up laser tag gun duplication
Changes path strings to actual paths. Changes relative paths to absolute paths.
Renamed several targeting vars to make their purposes more clear.
Fixed targeting not handling firing correctly for certain subtypes.
Adds Paramedic job as outlined on the forums. Reduces MD access to EVA,
adds some minor EMT clothing stuff, and fixes#8020 and the medgreen
armband while I was piddling around in sprites.
EMT alt title and indent fixed.
Now less broken.

The Icarus is now fireable in gun form. The point defense mode fires several lasers one after the other so that it can penetrate. The main gun mode fires a modified meteor. Also added an "abstract weapon" which has the projectile type settable for admin shenanigans.
Walls now lack an armor variable, which is replaced with buffed health. Normal walls take 4 shots with a normal laser or 5 emitter bursts to destroy. Reinforced walls now take 20 normal laser shots or 28 emitter shots.
Added some proactive runtime protection to logging for projectile impacts. Without a valid firer, the jump button is linked to the victim.
Moves them away from 'tie' legacy - path change, and different code files.
Changed single hastie var into accessories list, to allow multiple articles worn at same time. Updated all affected places in code to work with it.
Currently any number of decorative accessories can be attached, one utility (holster/webbing) and one armband.
* Refactors projectile Bump()
* Converts projectile_type var strings to paths
* Reorganizes bullet projectile paths
* Made a pass through all the bullet_act() definitions. Mainly ensured that damage_type is checked when dealing damage to certain objects. Removed stupid /turf bullet_act() override, replaced with on_hit() overrides on the relevant projectiles.
* Adds shotgun pellets projectile. Adds Raptor's shotgun slug sprite.
* Gives stunshots more of their own identity, refluffs them as taser cartridges for shotguns. They still aren't obtainable anywhere unless spawned.
* Makes projectiles pass through girders and cultgirders with a certain probability, unless the girder itself was clicked.
* Projectiles are also able to pass through grilles. Low damage projectiles have a chance to be blocked by grilles. High damage projectiles have a chance to have some damage absorbed by the grille.
* Makes projectiles for blanks invisible.
* Adds flash bullet types
* Adds support for 'penetrating' projectiles
* Swaps .45 and 9mm projectile types. .45s hit slightly harder, 9mils have more ammo capacity.
