PDCurses: filter out bogus double keypresses in combination with CTRL (refs #20)
* Has been observed on PDCursesMod/WinGUI when pressing CTRL+Shift+6 on an US layout.
I would expect code 30 (^^) to be inserted, instead PDCurses reports two keypresses (6^^).
The first one is now filtered out since this will not be fixed upstream.

* Since AltGr on German layouts is reported as CTRL+ALT, we must be careful not to filter those
out as well.
* This is active on all PDCurses variants - who knows which other platforms will behave similarily.
* You still cannot insert code 0 via CTRL+@ since PDCurses doesn't report it, but ncurses does not allow that either.
This _could_ be synthesized by evaluating the modifier flags, though.
