Shelter rc4

* Fixed not being able to shoot through some railings
* Fixed BLU's final control point not changing colour when captured by RED

Some people have reported cubemaps not appearing properly with LDR, but I've not been able to recreate the issue. Maybe the problem will magically go away with this new version.

* Fixed the map having no LDR lighting
* Added briefing photos

* Removed all custom content
* Detail tweaks

Only just found out this download got blackholed

"I will never update Shelter again" -me

I updated this map for inclusion in TF2 Classic. The original intent was just to give it a once-over to check I hadn't left in any custom content that was unaccounted for, but in the process I decided to sort out the last few niggles I had with RC1.

* removed custom content that I forgot to remove from the previous version

* replaced crates at B with wooden walls

* replaced concrete slopes leading to A with nicer-looking wooden walkways

* removed out-of-bounds clipping from spawn, so now you can run around on the upper level if you like (as little as that will achieve for you)

* various other detail tweaks

* uploading this as per request

* I forget the exact changes but there's HDR and stuff now

cp_pillowcase_b5:

* made new spawns (designed in part by Yrr)

* increased size of B capture point

* changed map instructions to say "capture all four control points"

* sentries and stuff can no longer be built under the planks on B

* detail improvements

* clipping improvements

* soundscapes!

* removed that side-route near A

* un-hollowed building at mid and removed stairs

* general detailing improvements

* clipping improvements

cp_pillowcase_b3

* major optimisation improvements (hopefully??)

* increased amount of health and ammo pickups

* fixed players being able to get out of the map boundaries

* decreased mid cap times

* removed windows from center hut

* more cubemaps

* detailing stuff

* some other things too maybe, I lost the changelog while working on this, oops

b2:
