* Changed so uba consumes command line option "/extractsymbols" and will use that to decide if symbols should be extracted from obj file
* UbaObjTool - Some cleanups and optimizations. Also added code just to get it in the version control (will remove again)
* Renamed symbol files from .sym to .exi (exportimport) to not collide with already existing .sym extension
