Removes a very large amount of world loops.
Adds a macro to painlessly generate a global list, and the needed code to modify the list when an object is made or deleted automatically.
Cleans up some commented out code.
* Tries to Please Travis
Should remove all active edge problems.
Moves map-specific unit tests to the map define file.
Enhances some PoIs in terms of adding /ignore_mapgen to the ground.
Fixes incorrect loot pile in one PoI.
* Conflicts are fun.
* Might fix unit test.
Tweaks Travis to compile all PoI maps in order to allow the compiler to find certain problems such as missing paths. This is needed because PoIs are loaded at runtime as opposed to being compiled like traditional maps, making them a bit prone to problems. Travis should help find those problems before they reach the live server by failing PRs which add a broken PoI map or break any existing PoI maps.
For regular use, the PoIs will not be compiled unless done so manually by the developer.
