The Great Renaming (#3014)
* move kekztech to a single root dir * move detrav to a single root dir * move gtnh-lanthanides to a single root dir * move tectech and delete some gross reflection in gt++ * remove more reflection inside gt5u * delete more reflection in gt++ * fix imports * move bartworks and bwcrossmod * fix proxies * move galactigreg and ggfab * move gtneioreplugin * try to fix gt++ bee loader * apply the rename rules to BW * apply rename rules to bwcrossmod * apply rename rules to detrav scanner mod * apply rename rules to galacticgreg * apply rename rules to ggfab * apply rename rules to goodgenerator * apply rename rules to gtnh-lanthanides * apply rename rules to gt++ * apply rename rules to kekztech * apply rename rules to kubatech * apply rename rules to tectech * apply rename rules to gt apply the rename rules to gt * fix tt import * fix mui hopefully * fix coremod except intergalactic * rename assline recipe class * fix a class name i stumbled on * rename StructureUtility to GTStructureUtility to prevent conflict with structurelib * temporary rename of GTTooltipDataCache to old name * fix gt client/server proxy names
