Invalid Byte Sequence

Nobody has claimed this yet.

When I try to create a new app with deano, I get an invalid byte sequence when performing a gsub on OS X ML 10.8.3

```

Start at lib/deano/commands/name_command.rb:25, where clean_string calls gsub, and follow the call from new_project_generator_command.rb:28-29. Reproduce the deano app-generation command shown in the issue and verify that project creation completes without the invalid byte sequence ArgumentError.
