Follows similar commits to the objectcache, rdbms, profiler, filerepo components and other areas [1]. * Remove duplicate descriptions from file blocks in favour of class doc blocks. This reduces needless duplication and was often incorrect or outdated, and helps (ironically) to make the file header more consistently visually ignorable. * Remove `ingroup` from file blocks in class files as otherwise the file is indexed twice (e.g. in Doxygen) which makes navigation more messy. * Remove `throws` tag for an undescribed MWException that isn't meant to be caught by callers.
