some useful tweaks, that make working with the OpenUserCSS.org more convenient
- displays version information for the themes on the profile page
- restores the images, that have been cropped by site, since they do not fit in the image container, and resizes the container for more accurate placement.
another advantage: these images support image zoom extensions
- changes the view to a more compact
- highlights the themes on hover
- on the profile page: displays statistics by default, adds screenshots of themes, adds an edit button to go to the edit page directly from the profile page
- on the edit page: removes variables (cause they is buggy now), makes the header (with save button) always available (sticky position)
- changes the start page to the search page cause the start page often throws an error
- use settings to enable/disable these options.
