Tremor

Few more map fixes. E1M2 being the major update, as it appears we didn't include the update version the last time around. Whoops.

Various tweaks and fixes in multiple maps, including softlocks, Winquake compatibilty and cosmetics. While perhaps not the final version, this should fix all the annoying softlocks people experienced.
It is highly recommended you use this version.

Managed to overwrite e1m4 with another copy of e1m3. Splendid.
This version has e1m4 included.

Critical errors in multiple maps (e2m1, e4m6, e4m7) hopefully fixed, while texture issues in a few more sorted out.
Seems like some people were getting crashes, so Khreathor has updated the progs. Also added in a few things to help manage whatever horrible softlock we missed.

impulse 51 - shotgun start mode
impulse 52 - give silver key
impulse 53 - give gold key
impulse 54 - give rune 1
impulse 55 - give rune 2
impulse 56 - give rune 3
impulse 57 - give rune 4

If you're in the start map and you want to get missing runes:
1) give yourself runes you are missing;
2) do: "changelevel start" to properly reload start map (don't do "restart" it will erase runes you just added);
