There are some times when we need a Switch Button (aka CheckBox) with more
than 2 states, generally to express check/uncheck/leave-as-is.
This patch extends the Button widget to support the new WBTTriState type,
similar to the existing WBTSwitch except it supports a 3rd state which is
reported to application as '-1'.
The implementation was done in order to not break the binary API. The
version have been incremented in the WINGs header to reflect the change,
but not the version in the 'configure.ac' because that have already been
done in commit c6e323e75d for the next Window Maker release.
