re #7889

For some versions of Qt (it has been seen in Qt4.8), the Update column of ScriptRepository was not
displaying correctly. By, defining the correct state values, this commit
solves this issue.

re #7889

Add a link to open the folder if the user wants, to give the user a fast way
to add, remove files from the repository.

re #7120

This commit deals with 2 points:

 * when you upload even small files it seems quite slow before the icons tells you it is done:
   * It is still slow the interection with the server.But now, it updates the icon as soon as the upload thread finishes.
 * After deleting the icon still tells you the file is up to date on the repo.
   * This used to occur if the user clicked on reload button while uploading. Now, this button is disabled.
