however this meant the invoke function could not modify properties for exec to use (unless it called exec directly after)
since the popup for eg would re-instance the python class each time.
now use the operator properties directly through rna without an automatic copy.
now an operator attribute is accessed like this...
self.path --> self.properties.path
- more detailed exceptions (always give file:line incase the python exception doesnt)
- fix some errors in the edit docs
editing docs still fails, need to figure out why.
