Simply removing the items from the rec_mon_table still leaves
a space since the table itself is still packed and the
global-vpacker uses a spacing of 2px.
So the rec-mon table has to be unpacked. explicit hide/show
calls in set_route() are also not helpful since the widget is
managed by a VisibilityGroup.
On tracks the bottom row of each mixer-strip has three buttons.
Two are provided by the gain-meter (automation, meter-point),
and the size of those is set in GainMeterBase (current 15x15px).
The track-group button size was left unspecified.
The master-bus only has the gain-meter buttons, and hence was
less tall compared to tracks.
Previously the bindings were given to the Region/* equivalents and made insensitive if there was no selected region.
Given that we have specific actions for nudge-playhead-*, and the ones in Region/ will always work on regions
if there are any selected regions, this provides a better set of possible actions, even if the naming is not
totally consistent.
This supersedes 0708cdb6b4, an explicit `name_label.show()`
is not needed. The inactive label was missing an explicit call
to show.

When ripple moving a region all the subsequent regions will be moved, next
region in the playlist after the dragged one first, last region of the playlist
last.
Thus, when an automation point is ripple moved along a region past the starting
point of the next region, it will be moved again along with the next region as
the move of the next region occurs after moving the automation point.
This fix reverses the sequence of the ripple moves, last region in the playlist
will be moved first, the next after the dragged one, last. So no temporary
overlap of regions will occur.
