Rename checkjobs.php to checkEMANRefineJobs.php to avoid confusion.

This checkEMANRefineJobs is linked by Xmipp and Spider recons, but I know that it only works with EMAN. The others link to it, because of a copy/paste situation. Also, checkEMANRefineJobs contains numerous things that only relate to EMAN.

I am creating a checkFrealignJobs.php for Frealign, so this will be named in parallel to the Frealign one. Eventually, we will need to create checkXmippRefineJobs.php and checkSpiderRefineJobs.php, but this is further off.

I did a grep of all files in the myamiweb/processing/ to look for this function.
