Virtual Spaces MWN

Time for a change! Virtual Spaces 2008 is now Virtual Spaces MWN.

This has several reasons, some of them are:
- Virtual Spaces is now based on the current Eclipse version Helios.
- Virtual Spaces uses Subclipse now and has full SVN client functionality.
- Virtual Spaces moved from oAW to MWE.
- 2008 is simply too long ago now ;)
