Polyfile

Updates to the command line interface to allow for greater flexibility in specifying output formats and output files. These updates are backwards-compatible, however, in the forthcoming v0.5.* release there will be a breaking change in the output: PolyFile will then default to the `mime` output format (to mimic the behavior of the `file` command) rather than the current `sbud` output.

This release also includes optimizations to the libmagic `search` and `string` tests which should result in significant speed improvements.
