removed unecessary code, added icons in-game

rewrote some of the code.

Pistol reserve ammo increased to 120 to compensate incapped while meleeing being removed (removed cause it was buggy)
Zombie move speed increased to 145 (slower than 150, faster than 135, you shouldn't be able to outrun zombies too easily)
Crawling speed decreased to 50% of crouching move speed to be more realistic (now it's 37.5 u/s)
Pipebomb decreased from 9s to 8s, bile jars also got hit with a nerf, for balancing reasons.

Melee range was increased from the default 70 to 90 (near 30% increase), this change was made with High ping players in mind.

I tested this with a friend who had 180ms ping and he struggled quite a bit with melees and the one hit down on Expert realism.

this should help.

Zombie speed has been nerfed to 135 u/s (60% of the speed of a healthy survivor), after testing 150 (66%, same as a injured survivor) move speed was way too unforgiving.
Incapped crawling has been nerfed to 45u/s (from 50) to compensate.
Pipebomb duration increased from 8 (vanilla is 6) to 9 seconds to compensate for the zombie nerf.
Bots will consider temporary health more before healing you or themselves.
sb_toughness_buffer 40 (used to be 30)
sb_temp_health_consider_factor 0.6 (used to be the default, 0.5).

Will do more testing tommorow when I play this again, but I think 135 is a good zombie speed value while still keeping it risky.

the og concept had it on 100 (45% of survivor move speed), way too slow imo but 150 (66%, 40< move speed) was way too fast.

Next values to try if I think 135 is still too fast: 125 and 130 (50% of a surv move speed under adrenaline)

no repeating realism cvars if "realism" base already selected.

Complete rebalance! Infected damage changes, ammo changes, director item spawn changes.

more zombies, since they're slower they get you through "volume", like in the walking dead.

balance changes, zombie movement speed now is 150 (from 100), crawling speed now is 50 (from 33) (33% of zombie speed)

z_avoidteammates 0 removed, incapped crawling speed increased to 33% for consistency.
