Removes the mimeutil project. This is an unused project that was meant to allow DuraCloud to do file format identification using the Droid tool (part of the FITS package). The code in the primary class was dependent on v5 of the droid-core project. The v6 version of droid-core is significantly different, so performing an update would require more effort than is warranted for a project that is not in use.
Minor pom formatting updates - no functional changes
