Houdini/Maya: 1. Moved binary plugins out of the helga package and into bin folder in order to be able to replace package without handle conflicts etc. Changed global_variables.py in order to point to these files. Nuke plugins is tbd, but is a bit more tedious because it contains git subrepos.
Nuke: 1. Removed git submodules from helga/nuke/setup/plugins
Nuke: 1. Deleted helga/nuke/setup/plugins dir in order to move it to bin/plugins/nuke
