Separate out 3D only stuff from Jpowder3D branch into new Jpowder_3D branch

This is my fault - basically the branch to develop the 3D features 
has not been kept up-to-date with smaller changes made to the trunk 
and also none-3D changes have been added to the Jpowder3D branch, which 
should have been added to the trunk first and then merged into the the 
Jpowder3D branch... So we have a little bit of a mess here.

To resolve this I suggest:

1) Manually (i.e. not through svn commands) copy all none-3D changes from 
Jpowder3D to trunk/code/JpowderViewer and commit these changes.

Jpowder3D was created at commit 323. 

2) Create new branch: branch/Jpowder_3D that is a copy of 
trunk/code/JpowderViewer

3) Manually (i.e. not through svn commands) copy all 3D changes from Jpowder3D 
to Jpowder_3D.

As long as the Jpowder 3D features are not in a mature state of being presented 
to test 
users it is VERY IMPORTANT that all none-3D feature changes are committed to 
the trunk 
NOT to Jpowder_3D. Such commits may subsequently be merged from the trunk to 
Jpowder_3D (using svn merge command). 
When Jpowder_3D eventually has matured it will then be straigthforward to merge 
the 3D stuff into the trunk, and,
more importantly, while Jpowder_3D is developed, other features can be 
committed 
to the trunk without messing things up even more.

It will be a pain to do this issue, but it will be even more pain if it
is not done
