Focuser Temperature Compensation - Focus Position threshold

With temperature compensation enabled, SGP checks between frames whether the focus position has to be corrected for temperature change. At present, corrections as small as 1 step are applied, if necessary with backlash compensation. This is unnecessary. We want corrections only be applied, when the Critical Focus Deviation [CFD] of the scope is exceeded. Furthermore the permission of smallest corrections may result in very frequent movements of the focuser, if the worst comes to the worst, after each frame.

This all was brought forward in a feature request that was put a year ago in order to fix this issue: http://forum.mainsequencesoftware.com/t/temperature-compensate-tolerance/4359
Then the proposal was, to introduce an user-definable threshold of temperature and/or time in order to minimize the number of temperature compensation corrections.

Hereby I put a similar, but slightly modified FR:
Please introduce an user-definable threshold of Focuser position (number of steps) as the criterion instead.
