Every .js file in the "scripts" folder of the user's data folder that
starts with a // ==QETScript== header becomes a command: in Projet >
Scripts, as a button on a new Scripts toolbar, and, because it is
registered with ShortcutManager as diagrameditor.script.<file name>, in
the shortcut settings, the shortcut bar (S) and command search. The
header gives its name, icon (a file next to the script or a theme icon;
a tile with its initials otherwise), tooltip, default shortcut and when
it is enabled (always, with a selection, with a conductor selected).
The folder is watched, so a script added, edited or deleted while QET is
open appears, changes or goes without a restart. A file with a header
that cannot be used gets no button; the Scripts menu lists it with the
reason. The menu also opens the folder, and holds "Exécuter un script…".
A click runs the script on the current project as one undo step named
after it, and asks to switch scripting on first, like "Exécuter un
script…" does: scripting stays off by default.
ShortcutManager::unregisterAction() takes a command out of the lists
when its script is deleted, and lets it come back under a new name.
