REVISION SUMMARY
  This differential is a hotfix for the recent work in the Focus module.
  One additional class, FITSSkyObject, was extracted and put in its own source files.
  The JMIndex parameter of the Centroid detection was not provided to the source extraction procedure.
  The Star Profile Viewer missed a few consts in its management of FITS data buffer, which caused some Jenkins builds to fail on SUSE and FreeBSD.

TEST PLAN
  Run kstars_ui_tests
