* Eliminate modal annotation warning dialog when generating a netlist fails
due to components that are not annotated.
* Add warning message to annotate dialog.
Fix also an issue on Windows, when using the footprint viewer or the component viewer in modal mode:
Reason: these frames (when run under the Kicad manager) have the Kicad manager as parent, and were built with wxFRAME_FLOAT_ON_PARENT style.
On windows, when the frame with style wxFRAME_FLOAT_ON_PARENT is displayed its parent frame is brought to the foreground, on the top of the calling frame.
and stays displayed when closing the frame in modal mode.
This issue does not happen on unix so we use now wxSTAY_ON_TOP on Windows, and wxFRAME_FLOAT_ON_PARENT on unix to simulate a dialog called by ShowModal.
This is not perfect, but at least it works.

* Change 'Silent mode' -> 'Always ask for confirmation'. Default on
(Same behavior as before, though arguably, it is very annoying and
should probably be default off)
* 'Automatically close dialog' -> 'Keep this dialog open'. Also changed
the default to _not_ keep the dialog open (what is keeping it open even
useful for ?)
* Change leave sheet hot key from back space to alt + back space. Note: for
some reason ctrl + back space did not work at least on windows.
* Add back space as delete node hot key which is consistent with the delete
track segment hot key in Pcbnew.
The DXF format polylines and lwpolylines have a 'flags' field of which bit 0 indicates if the polyline/lwpolyline is to be closed or open.
This flags field is correctly read during the import but in the conversion to board segments, was previously not used.
Now all are calculated using the top to bottom draw Y axis. This is perhaps not a good idea, but at least it will be easy to change, later.
Code cleaning relative to these bounding boxes.
