[FIX] website.snippet: can't edit website with firefox; remove firefox attr for media video is edit mode
[FIX] tour: display username in log for point of sale module
[FIX] website.snippet: before the save of the view clean_for_save is called. The option marginAndResize (called by twitter) try to bind events on the overlay but the builder don't load the overlay (for time perf). The fix set a default jquery empty div to avoid the error.
[FIX] website.editor: must display link information in linkdialox box. Remove /page/ and /page/website. from the needle to search page and apply real url as filter after the search
