Package for SPM8 (implemented for octave) 

SPM is the most popular softrware package for analyzing various types of brain imaging data. It is an invaluable addition to any scientific software repository. SPM8 (released as a live package) is the current stable version, and even though the software package was written for MATLAB most of its functions can also be used with octave (more on that here: http://en.wikibooks.org/wiki/SPM/Octave ).

Additionally to what I have written up to now in the ebuild I would like to add:
- A line which warns the user that the SPM GUI will _not_ work with octave
- A line which adds the /opt/spm8-9999/ directory to the octave PATH (system-wide)

I would be very grateful if you could help me with that, as I was unable to figure out how to do those things myself.
