Share TVB projects

We intend to offer in TVB a tool for reproducing and validating results published in articles.
Export / Import TVB Project seems to be exactly the functionality to cover this need.
We have Import/export already implemented, what is left:

• ensure good tests are done on import/export with multiple DataTypes
• decide upon a place where to place TVB-Projects
• add in TVB Web Interface a visible link towards the web-place where TVB-Projects are
• offer guidelines to people on this new feature
• should we allow people to add to this repository of TVB-Shared-Projects?

When taking care of this, we should also intensively test IMPORT/EXPORT of TVB projects.
The are still some problems in a few cases (like detailed in the log files attached to TVB-1102).
