This adds a few exceptions to the general preference
"Sound MIDI notes as they are being selected in the editor".
* Select all no longer plays _all_ notes.
* Remain silent when selection is inverted or a range is selected.
* Play no sound when a saved selection is restored on session load.
The existing code isn't wrong, but inefficient. If the selection is empty,
then this is necessarily the first note, and cannot be present in the
selection. So, don't search the std::set<> and then insert, just insert.
1. Alt is still handled to change drag behavior
2. Selection doesn't store notes unless they are part of the cut buffer, which means we should not
be altering the note selection in the editor's selection object most of the time.
* Always use InstrumentInfo for lookups.
Remove name lookups that directly used gui_property()
* Use set/get_gui_property() only to save/restore state,
push custom selection to InstrumentInfo.
* Only store custom selection, use unset for "default"

We no longer assume that Snap always uses the visible ruler lines.
If you want to snap to the grid, and ignore the users zoom scale, use SnapPref::SnapToGrid_Unscaled
This fixes 2 (known) oversights: "snap region(s) to grid" and "regions whose start are left of the canvas edge".
Separate Snap from Grid. Lots of naming changes.
Multiple simultaneous snap options allowed. Grid is one of the possible Snap options.
Grid uses the same data as the rulers. Replace complicated tempo_lines with simple grid_lines.
The Grid is zoom-scale-sensitive along with the rulers. If you are zoomed out, grid becomes coarser.
Snapped Cursor is a line that follows the edit point, and indicates where the operation will occur.
This replaces and extends the line that appears with the Cut tool.
New associated preferences: snap_threshold and show_snap_cursor.
