Add option to auto embed coverart image (bug 1742)

Refactored the code to be able to add filetype specific logic.
Until now we used only the mutagen abstraction to implement one
code for all file types, but this don't work for special needs
(e.g: coverart manipulation)

Gtk UI: Fix crash on OS X when truncating tooltip (bug 1825)

When displaying a long episode description in a tooltip in the
"New episodes available" dialog, gPodder cuts it at a certain
number of characters. However, Russian descriptions are regular,
non-unicode python strings, and gPodder may cut only a part of a
multi-byte UTF-8 sequence. Displaying such a string crashes
gPodder on OS X.

This patch fixes that by converting the description to a unicode
string if it's not unicode.
