Title: Default ctors for LED checkbox and LCD spinbox. Fixes for knob.

As it has been requested in the mailing list, this fix should bring the most important widgets with a default CTOR, so they can be used by qtcreator.

Contains fixes for the last knob patch.

This patch runs fine with valgrind, probably error-free.
