Subject: [PATCH] Separating lalt_lshift_toggle option

https://bugs.freedesktop.org/show_bug.cgi?id=43922
Now, alt_shift_toggle is composed of "right" and "left" blocks.  Also, it is one-direction ("Next") only.  For people who need both directions, the "bidir" option is introduced but not advertised in xml - because GUI tools usually belong to DEs that perform one-way circular layout switching.
