ADLERNEST ROOF Version:beta 1

Adlernest Roof B1 - Modified with DerSaidin's permission.

Alternations:
- Roof access added from CP spawn and axis spawn after the controls are blown
- Added access to the abyss with rope exit leading to under axis spawn
- Bug jump on the roof removed
- Added rocket launcher (can be used once only), which creates a hole in the roof (near the ammo packs)
- Removed walls next to the ammo packs
