Add a new signal activate-item-alt to KatzeArrayAction which has
a button argument specifying the mouse button that was pressed. If
this signal is handled one can special case middle or right
clicks, and return TRUE to suppress the emission of activate-item.
The browser utilizes this to open new tabs when middle clicking
on bookmark menu items.
Some refactoring in KatzeArrayAction and the addition
of a function to create arbitrary bookmark tool items
allows us to easily revamp the bookmarkbar so that
it finally reflectls changes to the bookmarks,
including adding and removing items.
KatzeNet can from now on be used where
URIs are handled and one would have used
libSoup and/ or local file handling as
appropriate, whereas KatzeNet does both.
Since we are displaying icons in several
places KatzeNet also provides an icon
loader that saves us from doublicating
even more code.
All bookmarks and also history items have
icons now, since KatzeNet makes that
incredibly easy.
Search engines are also using favicons
now, and right now custom icons don't
work, we still need to fix that.
Note that only icons are cached, nothing
else and the code is known to have a
hidden, hard to reproduce crasher which
may appear when an icon is newly loaded.
Property name localization is only useful if the
strings are meant to be used in a user interface,
such as is the case with WebSettings, or for
graphical interface builders, which are not of
our concern, since we don't use Glade and friends
and nobody else is going to use our widgets.
In short, make translation work much easier.
Finally the trash, which was the last item that
needed to be implemented as an action, is an
action, a KatzeArrayAction to be exact.
This simplifies more code and also makes Window
and RecentlyVisited generically implementable.
Incidentally this change also fixes a bug where
the browser tried to add a new tab when the last
one was closed, even while destroying itself.
Furthermore sokoke_image_menu_item_ellipsized
and sokoke_widget_popup were promoted to Katze.
We're still keeping the old functions for now.
