Set the updateURL automatically when the user uploads the script

[Francesco Bedini]

For security reasons, the repository should analyse the script file and remove any // @updateURL http://<path> line that is found there and change it or add the // @updateURL http://code.waze.tools/repository/<id> In this way if the author releases a script with malicious code it's possible to push a new version and the script gets deleted from the "infected" clients. Moreover in this way the uploader doesn't have to remember to change it after loading the script file.

[WazeTools Suite]

The (eventually present) UpdateURL parameter is now substituted with the correct one pointing to the Waze.Tools CODE site
