Renamer 0.1.0

Renamer is a command line script that renames files using a
ruleset. The rules can include:

--remove: finding fixed strings and removing the matches
--fixed-string: searching for fixed string and replacing the matches with other
strings
--perl-regexp: searching with regexps and replacing the matches with other
strings

Renamer will recurse through directories (--recursive) or even rename
them as well (--directories). It also has an option to print the
changes that would arise from a ruleset without actually executing
them (--dry-run).
