Increase Render Distance

- Increase base draw distance to 5000.
- Increase max draw distance to 15000.
- Add medium draw distance for certain levels.
- Remove cyclorama from depth buffer.
- Remove cyclorama requirement from gLevelClearColor.
- Change the type of gNumEnemyOfKind to int32_t.
- Raise MAX_SUPERTILE_ACTIVE_RANGE to 20.
- Change all values in gLevelSuperTileActiveRange to fit in the 8-20 range.
- Raise MAX_LIQUID_MESHES to 255.
Issue jorio#24.
