This should fix saving of preferences when the rc file does not exist
yet. Note: always test things with a clean configuration...

The html files were all generated in the top source directory and all
had the same name, so only the last generated one was accessible.

Thanks to Mike for noticing this function.

The text was copied to the primary clipboard and was thus only
accessible via middle click.

As Mike explained to me, this is useless. The clipboard manager will
automatically take the image when the application is closed.

This caused xfce4-screenshooter -r to be unusable as a command for a
keyboard shortcut, as the keyboard was already grabbed by the thingy
which launches applications from shortcuts. Escape is still not usable
in that case, but that's normal as we don't grab the keyboard...

Instead we launch that action directly, supposing that if the user
specified an action, he expects it to be used and not to be asked
again what he wants to do.

Do not use the frame extensions to get the screenshot of a window,
but use its shape instead. This allows us to have a transparent
background under rounded corners instead of the window that is
under the screenshoted window.

Fallback to the XDG image dir if it's not valid.

Fix build with full debugging and plug a leak.
