[Enhancement] Import/Export functionality for configuration and mod list

[hermaherp]

Just a suggestion to add a feature to import/export configurations of the mod manager in case a backup is needed, with said backup storing the configuration of the mod manager as well as the list of mods installed which, if possible, should allow the user to automatically download mods, or perhaps store and compact the mods into a zip/7zip. It may be possible to also store mod configs individually since each mod works using a pdb file and a config to check against the defaults, so I'm trying to keep my suggestion within a reasonable expectation. For a formatting implementation idea, it could be a JSON file storing the data needed for the mod loader to read in sections and process the information as needed, and is stored within the compressed backup or standalone depending of whether or not mods were also added into the backup
