* Another rather large overhaul of the battlegrounds.
- in bg_common.txt, stripped out several more NPCs, split them off.
- Most of the NPCs in bg_common.txt are now official Aegis versions.
- Completely rewrote Tierra Gorge for the most part, from ground up.
- Moved old Tierra Valley battlegrounds to /custom/battleground.
- Added Tierra scripts, Flavius, and bg_common to scripts_athena.
- Tierra, KvM, and bg_common scripts are now enabled by default.
- To use custom Flavius, you must enable /flavius/flavius_enter.txt
- * TIERRA GORGE AND KVM BOTH REQUIRE TESTING *
