Remove, rename, and/or deprecate relevant classes

The scifio-devel and loci-legacy components are removed in favor of loci-common (which is renamed to common).  Various classes that were deprecated in 4.4.x are now removed, including bf-itk and some OME server classes.

There is still a fair amount of renaming to be done, but I'm opening the PR for now to test the breaking build.
