Terminal block manager: say that it is opening

Browse Source 
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.
