-U only removes related tiger files. Fixes #8.

--UNARCHIVE and `Unarchive and Remove Tiger Files` in the GUI now only
remove related tiger files (created by the archived file). The output
directory can still be cleared with `Remove Tiger Files`.

When a file is archived, a list of created files is created and saved
to `<archive_file>.info`. These info files are removed when unarchiving.

This solves issue #8.
