chaotic era 1.6.3: auto-siphoning and bugfixes

welcome to chaotic era 1.6.3

here's what's new:

- added automatic siphoning tech: low-charge units automatically siphon nearby power sources - added wireframe boxes around selected units for better visibility - made numbered build shortcuts unit-specific (ie. "2" will always build a scanner) - lowered default zoom - changed venting to no longer work during siphoning - decreased initial siphon speed - increased barricade damage - fixed AI building on tiles outside the map area - more small tweaks and bugfixes
