Fix for issue #2, cryptic failure message.
Fix for issue #2, cryptic failure message.

Previously when the dictionary was not installed to
/usr/share/namealizer then the script would fail unless the user
provided a --dictionary option. The failure was pretty cryptic and
basically useless.

I've made two changes that should keep this from being an issue.
1. The script now ships with the dictionary in a default position which
is used by the script unless the user provides --dictionary.
2. In the event that an invalid dictionary path is provided the script
should raise a DictionaryNotFoundError.
