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
Previously, if $PATH contains whitespaces the startup script would split
the new exported $PATH on the first whitespace. This was observed on an
Ubuntu system where $PATH contained a directory with whitespaces.
The change adds weak quotation around the new path to prevent expansion
of whitespaces. $PATH though, is still expanded.
This properly sets the port-latencies of PluginInsert owned ports as well
as handles external sends (send-target playback latency).
NB. This needs more work to ensure that Sidechain input port playback
latency is set before the feeding send queries it the connected latency.
Re-ordering process may change sidechain or external-send latencies,
but since re-ordering does not change the route's latency,
engine.update_latency() may not be called.
If the copy c'tor of ProcessorSelection was actually used,
assigning the XMLProcessorSelection
processors = other.processors;
would lead to duplicate free() of the XMLNode*
XMLProcessorSelection would need a dedicated copy c'tor that
duplicates allocates a new XMLNode.
see also #10 at https://www.viva64.com/en/b/0540/
Anyway, the copy c'tor and assignment is never used. This commit makes
this explicit.
