Development branch is now 0.7

Written for Gephi by Mathieu Bastian on 2009-06-27

Until now the development branch (i.e. trunk) was belonging to the 0.6 serie. In order to set the 0.7 as the development branch following operations has been done:
* Latest 0.6 changes were merged to the 0.6 branch in the 0.6 serie.
* Development branch was deleted, because all changes has been merged in 0.6.
* The 0.7 branch, so far set as "Experimental", was moved as current trunk.

These changes should affect current developers.
