One pass of the event loop after show() was not enough: the message box
was not painted yet when the long work started (seen on Wayland), only
the busy cursor was visible.
Wait for the window of the message to be exposed by the window system
(500 ms at most), then paint it before building the manager.
Opening the terminal block manager reads every terminal of the project,
and builds the folios not built yet (lazy folios): on a big project it can
take a while, and the user could think that nothing happens.
TerminalStripEditorWindow::instance(), used by the menu action and by a
double click on a terminal strip of a folio, now shows a busy message
("Opening the terminal block manager...") and a wait cursor while the
window is built or switched to another project. Moved from the header to
the .cpp file.
In the terminal strip manager, free terminals could only be moved into a
strip with the "move to" list and its button. Dragging one onto a strip,
which is what users try first (#409), did nothing.
Free terminals can now be dragged onto a strip in the tree on the left,
from either place they are listed:
- the free terminal table: every selected row is moved;
- the tree itself: the dragged free terminal is moved.
Dropping on a strip, or on a terminal already in that strip, moves them
with the same undo command as the button, so one undo puts them back.
The strip is then selected, showing the terminals just added. A drop
anywhere else is refused.
A drop is also refused while the free terminal table has edits that are
not applied yet: moving reloads that table and would lose them. The
button is disabled in the same case.
The drag carries the uuids of the terminal elements under its own mime
type, and the tree only moves terminals that are still free in the
project when the drop happens.

Before this this commit the terminal strip editor couldn't only work on
the first project opened into this editor, all other project opened
after couldn't be edited.
This is now past, terminal strip editor can now edit every project open
in QElectroTech.
