(issue1579) Fix axes syncronisation at Gauges
The SyncNumberAxis was completely broken. It only synced
in one direction and even that did not work correctly when
data was added to the axis (and the syncAxis rescaled but
forgot the old axis) then there were lots of ways to bypass
that scaling. And i also think the trans calculation was wrong.
It has been replaced by a "mostly" simple method to just keep
the W in M and W in CM+Datum axes in sync. I say "Mostly" because
it had to deal with the Bounds interface.
