arena_oilrig b12

Adds a hall under the ramps and next to point, don't know if they are permanent or not, needs a bit of playtesting first. i also added some weird looking decoration, probably going to make it look better later. added a bit of trim, needs more though. going to add pictures soon.

Adds a few details, cleans the place up a bit, and then a slight change to the ramp at spawn. This is no where near done, still have a bunch of places to make look nice, and definitely needs work to the background and water

ive removed the wall on the first platform on the left of each spawn, and made it look a bit more realistic. you can also jump the fence as scout and explosive classes. removed a bit of prop spam and added grates at the bottom of ramps

Most of the textures were inconsistant on each side, i clearly missed some spots and in one case an entire room. i was tired yesterday. This fixes all that, and im still likely to have missed a bunch.

I added some textures and addressed some of the feedback given during the imp this was played on.
