VESPERS: Changed the ccd motor, single element vortex motor, and the four element vortex motor to use the encoder since they do actually have one.  Not sure how I missed that before.  Fixes #311.
VESPERS: Added a moveStartTolerance to all the sample stage motors because they were getting caught in the weird moveFailed state from AMPVwStatusControl if there isn't a moveStartTolerance set.  Fixes #314.
VESPERS: Turns out I accidentally had the motorsChanged() slot after the connect statement.  That wasn't necessary and was causing non-db-saved values from showing up in the view if it was opened from the db (from say, the workflow).  Fixes #313.
