Add community Battle Lab & Concrete Bunker assets (#836)

Adds community assets for a Concrete Bunker and an Allied Battle Lab (GATECH01). New binary art files were added (concretebunker.pcx and multiple SHP files for gatech/ggtech variants). art_cncnet.ini now references the concrete bunker cameo and introduces GATECH01 with its animation sections; rules_cncnet.ini registers the new animations and the GATECH01 building type and full building definition; EditorRules.ini categorizes GATECH01 under "Community Structures".
