Bug 18052 - fix setting the rescan time in the classic UI
Silence a noisy backtrace: only complain about falling back to single
audio dir when there actually is more than one defined.

Skip trying to map xml/html code to file paths. Playlist parsers often
do this when they fail to fetch a playlist and receive an error page
instead.
Minor tweaks to the web UI

- make EN skin look slightly less ugly
- improve UX on mobile devices using EN skin
Changelog update
Disable some test code
MSIE 11 now return empty cookies as an empty string instead of null
Return quickly if cache already has been initialized
Two more cases where we can end up with non-absolute URLs. Make sure we
add the "webroot" in those cases.
