BuildFilterOffsets refactor

Refactor the Build Filter Offsets utility. BuildFilterOffsets object moved from FilterManager to buildfilteroffsets.cpp/h/ui Remove lock filter / dependent filter concepts. Allow user to specify the reference filter to use to build offsets against. Fixed bug whereby Focus wasn't resetting focuser position after BuildFilterOffsets was aborted. Fixed i18n bug. Added functionality to Adapt Focus to temperature / altitude for AF run solutions.
