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
