The old hack doesn't work any longer, there is only one cell layout in
GTK+ 3.x, not separate ones for the button and the popup. Switch back
to recreating the cells in notify::popup-shown.
Also simplify the code, we only need to remember one cell renderer in
our struct, and remove manual resizing code that was only needed in
older GTK+ 2.x vrsions.
Registering a full menu path as a procedure's menu label is now
forbidden and causes the procedure to be rejected.
Bump the plug-in protocol version so a pluginrc containing such cruft
is not used.

For various reasons, (gimp-context-get-brush, pattern, gradient, ...)
can return "Standard" which is the untranslatable name of the internal
fallback object.
Therefore, we must accept "Standard" as fallback in all PDB functions
that take brush, pattern, gradient etc. names.
...and successfully fails
Commit d2ad2928 removed "gradient-repeat" from GimpPaintOptions, not
considering that it is also used in the PDB.
Move "gradient-repeat" from GimpGradientOptions back to
GimpPaintOptions, and add a comment that it is only used by the
gradient tool, not for painting.
Don't destroy the color frames when the number of points changes.
Instead, simply hide them so they keep their color model, but add an
upper limit of an arbitrary number of 16 frames to keep around.
I know that the idea of black toilet paper is traumatizing nomis! ;-)
So here it is, using the CSS "!important" trick to override GTK+ CSS
recoloring code.
In order for the icon to be always visible, even on light background, I
am adding a path around the toilet paper shape (which this time will
be properly recolored by GTK+ with the foreground color, hence making
the icon clearly visible).
The extension dialog will show details about an extension (long
description, screenshot, upstream URLs, etc.) with this widget.
Update the GimpExtensionList to send a "extension-activated" signal on
double click, and make the extensions dialog react on it to display the
extension details for the activated extension.
This is all still mostly a skeleton GUI, but it is starting to get into
shape.
This is using GTK+3 widgets, so I make sure to keep it well separated
from core code. The gimp-2-10 version will have to rework the GUI, but
the GtkListBox and GtkSwitch are nice and make things easier, so it is
worth using them here).
