Release of XStudio 0.7

The final version 0.7 of XStudio & Xagent is available for download at the usual location: http://www.xqual.com/support/download.html

Only one minor bug has been reported on 0.7b3 and has been fixed (about filtering tests while creating a campaign). The user's guide has also been slightly updated (including results about memory consumption).

I already started working on the version 1.0 and it looks quite promising! Hence, my first tests on optimizing the TREE RETRIEVAL METHOD is showing HUGE progress in terms of performances :) 

At the end it will be visible on:
- time to start the application
- time to refresh the tree after a change has been submitted
- usability over VPN or any slow networks

Even using local Database, time to retrieve/refresh ALL the trees has been reduced by 80% (3.8s to 750ms in my case).

But note that...
- the biggest the trees are (the more branches and leaves they contain, the biggest will be the improvements (in percentage)
- the slower the connection to the database is (i.e. if the database is hosted remotely through a VPN), the biggest will be the improvement (in percentage).

I will do more tests but I presume, improvements could reach more than 95% in some very usual environments.
