gtk_menu_shell_insert() is a virtual function that was being directly
invoked from the class vtable.
Turn it into a proper signal and emit it in the usual way.

This makes the behavior identical to other widgets which
handle button presses, and it avoids problems when placing
switches into a windows main toolbar.

We have meaningful labels for the Ok buttons in all other choosers,
so just use the same string we use in the app chooser and the
font chooser.
Also move the mnemonic from s to a in 'Saturation', to avoid a
mnemonic conflict. String change !

This is done in the same way as GArray was replaced with GSequence in
GtkTreeModelFilter, in a patch done by Xavier Claessens.
All sorting code has been reworked to use the GSequence sorting
and insert sort functions, instead of doing a lot on our own.
Significantly improves performance when e.g. removing (filtering) a lot
of rows from the filter model. Fixes bug 616871.
This commit includes changes by Kristian Rietveld to make the patch apply
on top of the treemodel-fix branch and pass all newly written unit tests.
This allows for more thorough testing of "has child" filter functions.
We also test a has child filter function with a sort model as
child model, to verify that we receive enough signals to function
properly.
The filter model is now more strict about the signals which are emitted,
so the base tests have been expanded to test with both the root level
nodes collapsed and expanded.
- Before we kept a reference on all nodes in non-root levels. This has
been changed, now we keep a reference on the first node of each level.
If, due to changes in the model, another node becomes the first node in
the level, the reference is transferred to this new first node.
- All non-root levels keep a reference on their parent.
- By making use of the external ref count, the filter model now emits less
unnecessary signals.
- GtkTreeModelFilter does support filter functions which decide visibility
of a given node based on the number of or visibility of children.
To accomplish this, a child level of a node is cached when its
parent has an external ref count > 0, because changes to the node might
affect this parent.
- An optimization for not building the root level in case the inserted
node is not visible in gtk_tree_model_filter_row_inserted() has been
removed. In this case, we still need to build the root level and
possibly a child level to monitor for signals which might make
this row visible.
In gtk_tree_model_filter_check_ancestors(), also handle the case when
a node is already in the cache, but invisible, in the root level.
With the upcoming changes to GtkTreeModelFilter's ref counting this
case can occur.
