New Features

• Added behaviour trees (mixed with utility function which allows dynamic reordering of nodes based on a per-tick utility evaluation)
• Added grids and fast ways to cast "rays" inside grids (ie. to determine how far a unit can go before colliding)
• Additional "approximate" behaviours for the simulator: Kind of in-between evaluator and simulator regarding performance and result quality
• Added option to skip frames in simulator to improve speed whilst reducing the quality
• Added basic Reservation implementation for GMS to make Gas-Mineral-Supply management easier

Fixes

• Fixed DBScan clustering sometimes assigning a unit to multiple clusters
• Many bugfixes in simulator regarding stealth, and power of (protoss) units and spider mines

First "release", compatible with JBWAPI and BWAPI4J.
