Finishing the extension registry feature

[Jan-Oliver Wagner]

Hi,

finally I really aim to finish the extension registry
feature.

The most important remianing problem was that the __init__.py
of a extension should not contain any GUI relevant imports
or otherweise the test suite has a problem.

On the other hand I wanted a single standard line in
thubanstart.py for each extension to load completely.

My proposal now is to define a filename (Extensions/myname/all.py)
where all imports are done to fully integrate the extension
into Thuban.
Then, in ~/.thuban/thubanstart.py there are lines like:
import Extensions.gns2shp.all

This allows for later automized loading of all available Extensions
(which is one of  my goals).

What do you think?

	Jan
