* callbacks are unregistered during session-deletion, skip saving them
during session destruction.
* prevent duplicate state restore, re-load script with the session, not
window instance.
Previously EditorAction and ExitorHook scripts were saved with
instant.xml. The were saved with each session and in the config
dir (for new sessions). This allowed inconsistent UI setups, especially
when loading old sessions that had no or different scripts.
Now Editor scripts (actions and hooks) are saved in a dedicated file,
session-independently. This goes along with ui_config in general
e.g. action-table-columns
The scripts are not saved with ui_config file for two reasons:
ui_config settings related to built-in ui_config_vars.h,
and in the future there may be further indirection like "ui-rc-file".
Note: previously loaded editor scripts are lost with this change.
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.
Removed the term "Lua", because users were turned off by something they didn't understand.
A special-case Lua script ("Shortcut") allows the user to select an arbitrary Action.
The "Shortcut" script is selected by default, and in this case there is no "Type" or "Author" displayed.
Action-Buttons may still trigger Lua scripts, as a secondary function.
* register bindings for action_param
* honor pre-seeded value (don't ask)
* allow to pre-seed a script-name
* allow to cancel interactive script load at parameter-stage

We can't use Lua to construct a PBD::SystemExec Obejct. Lifetime of the
object is bound to the Lua interpreter or local function scope.
Destroying the C++ object terminates the process.
Additionally to adding a dedicated method, we also override the existing
os.execute Lua libary method with a rt-save (vfork, close filedescriptors)
wrapper.
Lua serialize() is called recursively and concatenates strings.
(in Lua that results in a new string on the stack, with 2 unused old
strings). Collecting garbage every time becomes expensive, so do it
only once at the end. GUI scripts are not memory limited anyway.
