So after a good coffee, here is my proposal:

  1 - Move the upgrade code from trackview to documentvalidator (which 
is a more logical place for updates to the document)

2 - Put the upgrade code in a different xml file, called like the 
kdenlive_id of the effect, for example frei0r.balanc0r upgrade code 
could be in a file called frei0rbalanc0r.upgrade

3 - In documentvalidator, we load all upgrade xml in a QMap <QString, 
QDomElement> using the file name as key.

4 - In documentvalidator, we parse all effects and if we have a version 
under the current one and the effect has an entry in the previously 
created list, we trigger the update.

What do you think about that?
