#2 plugin dependencies and nif export/import

[Stefan Thierolf]

Hello,

Let's say you want to make a plugin for MW standalone
and you forgot to uncheck MW Tribunal/Bloodmoon in the
TES-Editor.

I don't know if this feature is supported, but I think
it would be nice if you can change the
plugin-dependencies after you have finished a plugin
with TES Editor.

The other thing is the nif to 3ds-tool. I think it
could be very useful if you can go the way back, i. e.
from 3ds to nif.
