Bug Fixes in Educational
Fix UI bugs in the Options window, Catalogs tab. Certain controls (the star magnitude limits and
deep-sky catalogs) did not enable the Apply button when modified. The deep-sky catalogs changed
the map immediately without needing Apply or Ok, which is inconsistent. Now these controls behave
like all of the other options: Apply, Ok, and Cancel should all work on them as expected.
Thanks for pointing this out, James.
