Update CLI

This replaces the older style prompts with fancy ones using CLI::UI. It also removes the colorize dependency since CLI::UI provides colorizing functionality.

This also changes the actual clone from an exec to a spawn so that we can output a little extra at the end. This has a side benefit of telling us how long the operation took, since it was wrapped in a frame.

Rails 5 support

Merge pull request #7 from snkutkoski/development

Rails 5 support

v1.1.0

There were a handful of file paths with hyphens in them (db-clone) which weren't getting loaded by Rails properly because 'db-clone'.camelize returns 'Db-clone' instead of 'DbClone'.

The usage has changed in that Gemfiles now need to use gem 'db-clone', require: 'db_clone' instead of just gem 'db-clone'.
