* A new zim module has been added, this module allows several things to interact with Zim files. * Allow searching of Zim files using libzim. * Allow downloading of Kiwix projects (wikipedia, wikibooks, etc) on a schedule which replaces the outdated files. * Creation of a new zim docker container which allows viewing of the Zim file contents. * This commit also adds move/rename/mkdir features in the File Browser. * File tags are preserved when moving/renaming.
