cross platform dynamic path selection
Merge branch 'master' of https://github.com/SpaceBlender/USGS

* 'master' of https://github.com/SpaceBlender/USGS:
  Reverted changes. Progress was not showing in GDAL operations. No need for dynamic naming scheme as Blender has fixed location in all systems, and temporary files always stored in current working directory. Plugin was causing errors so put back to stable version so everyone could get it working.

Conflicts:
	UI_Module.py
	gdal_module.py
