New Features:
-------------
(1) Adding the possibility to structScones to re-tag all the previously processed files using scones. This is particularly useful when you want to change the number of isAbout links you want to keep for each tagger documents. Also, the user now has the possibility to add "free tags" on the fly that doesn't rely on the Scones tagger. So the workflow is as follow: Scones tags the document according to its loaded ontology. Then the user can add some more tags by hands. The user also has the possibility to re-process a text file that has previously been processed using the same UI. The only thing he has to do is to edit the text, and re process it using scones. Note: the previously tagged terms will remain in the re-processing process.
(2) Making structSearch aware of the structScones module. If a result, within a displayed page is detected to be editable by Scones, a "Scones edit" icon will appear if the user is logged-in as an administrator.
(3) Making structBrowse aware of the structScones module. If a result, within a displayed page is detected to be editable by Scones, a "Scones edit" icon will appear if the user is logged-in as an administrator.
(4) Added a "dataset selection" option in the structScone module
