Ports the Maven build POMs to Gradle build scripts, which are a bit
friendlier to use. Instead of using the exec:java Maven goal to run the
server now, the gradle run task should be used.
This commit implements collision detection using the map files loaded
from the cache, and adds support for modifying the collision matrices at
runtime when the game world is updated.
All checks to see if a tile is reachable should now be done via.
World#traversable, instead of Region#traversable, as the World object
can handle checking tiles across multiple regions. These are done for
the WalkingQueue and Pathfinder implementations.
Refactors the map file loading code by importing existing code from the
Vicis cache editor project. Adds classes for decoding objects and tiles
for a given map file index. Only the new MapIndex decoder code is used
when loading GameObjects at the moment , which will later be updated.
