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.
Fix crash when :
1°-Open a project with terminal strip and open the terminal strip editor
2°-Close the terminal strip editor and the project (keep qelectrotech
open).
3°-redo step 1 and click on an item in the tree at left of the window,
qet crash.
Qet don't crash anymore but the terminal strip editor continue to work
with the terminal strip of the first opening (exactly the pointer of the
terminal strip) who don't exist anymore. Need more work.
Since this commit, the terminals can't be moved from the tree widget,
instead we need to use the "move in" widget to move one or several
selected terminals in the table view.
