MidoriView is the only place where icons are and should be
loaded, elsewhere we just use cached icons.
midori_view_get_icon_uri allows distinguishing whether a view
has an icon or a default icon, and using the filename.
The preference determining where to open those windows
is not currently honored, so everything goes in a new tab.
Incidentally compile time checks guarding the web inspector
are replaced with runtime checks here, and the same
approach is used for the create-web-view signal. The
features are used if available.
We are not literally undoing in the sense of
reverting, this is actually about undoing
the individual parts of the last refactoring
that implemented the socket/ plug logic.
As turned out, the idea was nice but the
implementation was absolutely not, embedding
of processes in a graphical way is not
at all reliable enough for complex use cases.
Naturally this change should solve all sorts
of peculiar issues, including actual
regressions in functionality. Relieving.
The approach is rather plump, Midori can be
run in a plug mode that creates a GtkPlug,
while the normal instance knows how to embed it.
Communication between browser and tabs is
done via named pipes which are portable.
The feature is not complete right now, there
are expected regressions, but it works.
As a bonus, we implement Not found pages.
