Replace our custom entry widget with one based on gtk.Entry

Browse Source 
Our custom entry widget, which was based on sexyicon, did
support placing an icon in the entry (e.g. the magnifier icon
for the search entry) and displaying progress in the case of
the url entry in Browse. Both is supported since GTK+ 2.16 in the
gtk.Entry.

The patch does keep the old API, that is why we can land it in
0.94 no change in the shell needed only a small change in Browse,
in a second step I would like to use the upstream API e.g.
's/set_icon_from_name/set_icon_from_icon_name'.
