Add an automatic import which groups the free terminals of a project
by the part of their label before the first colon ("X1:2" goes to the
strip "X1"), creates the strips missing and sorts the terminals in
natural order, as one undoable step.
The import runs when the terminal block manager opens on a project and
can be run again from a new toolbar action. It only adds : the strips
already known keep their terminals and their order, and terminals
without label are left free.
The manufacturer chosen to filter the terminals of the Width column is
stored in the data of the terminal strip (information "manufacturer" of
terminal_strip_data, written only when set), and selected again when the
strip is shown in the editor. Each strip keeps its own manufacturer.
Older versions ignore this information.
TerminalStripEditor::apply() now starts from the current data of the strip
instead of a new TerminalStripData: the uuid of the strip was replaced by
a new one at each apply, and the new information would have been lost.
