Added:
- New base class for the AMActionRunnerCurrentViews that does most of
the model work.  It appears that both views still work with the new
super classing.  They now only really worry about the visual aspects and
setting text labels.  The rest is handled by the new
AMActionRunnerCurrentViewBase.
Merge branch 'master' into Issue630
Altered:
- AMScanAction, AMScanActionController, AMScanController, and
AMActionRunnerBottomBarView to properly display more relevant status
information for scans.  It will now show "initializing", "running",
"cleaning up", and "exporting".  Tested and appears to work as intended.
