add all the zip files in the current directory to the python path.

Modules will be loaded in alphabetical order. Once all zips are added to the path,
each zip file which contains module with the same name (CASE SENSITIVE) itself will 
automatically be imported using "import <zipnname>". All side-effects will happen
inside a maya executeDeferred call (so the maya environment should be fully loaded).

It's a good idea to be very sparing in the use of auto-loading modules!
