This fixes a crash when selecting a section, and then changing
the time-selection. Previously it was assumed that the section
context menu can only be shown for sections. But it applies to
any time[line]-selection.
Previously,
0 -> no swing (1:1, 50%)
50 -> triplet swing (2:1, 66%)
75 -> hard swing (3:1, 75%)
100 -> sextuplet swing (5:1, 83%) (default!)
150 -> absolute maximum (inf:1, 100%)
This is rather confusing...
One common interpretation uses percentages of the beat, where triplet
swing is 66%. However, that causes precision issues since it's really
66.666...
Since we already default to 100 and take "no swing" as zero, let's make
that reference point triplet swing. Then the scale becomes:
0 -> no swing (1:1)
100 -> triplet swing (2:1)
150 -> hard swing (3:1)
200 -> sextuplet swing (5:1)
300 -> absolute maximum (inf:1)
300 doesn't make any sense, so let's change the range to -250 .. 250
which covers all useful values.
Also remove the division through 100 and back, to avoid rounding issues.

This also adds interaction with sections in the
Arrangement Ruler.
Note that selecting a range switches to the Range tool.
This is enforced because time-range selection is only meaningful
with tools that perform edit operations on the whole timeline.
Create a marker by ctrl-click, hover over it and then ctrl+z
undo. This used to crash in Editor::get_preferred_edit_position()
gtk2_ardour/editor.cc:5179, checking for entered_marker->position()
This prevents overlap of successive hits.
Ardour 7 added a new duration select drop-down menu,
which defaults to "Auto" (musical grid) and removed
the special case when drawing percussive notes.
It was possible to accidentally create overlapping notes,
without the user being aware of doing so.
These were being drawn in a way that failed to really convey relative
tempos very well. This is now better, though perhaps there are other
improvements possible
