Export and import all of SaraSortd's configs

Settings > SaraSortd can export GlobalConf.toml, both templates and every
directory's config as one file, and import it again. An import backs up
the current configs first; directories that don't exist can be given a new
path (InputDir/OutputDir, ValidInputDirs and the config's own name follow)
or made.
