Extended the easter egg area considerably. Fixed some bugs. Removed some needless area portals.

No changes. Repackaging in hopes to fix the problem encountered by Test Chamber Junkie where some assets did not load. It may have happened because I tried this chamber with a clean install at some point that was missing said assets, and I can't remember whether I repackaged the map in that situation.

Added a clipbrush that prevents an unintended solution in a certain part.
