The `guard_all!` method is never called, and `guard!` is not implemented. The
`doorkeeper_guard!` method is also never called, and is mostly the same as its
non-bang counterpart.
- Fix naming of API::CommitStatuses
- Ensure we use require_dependency instead of require
- Ensure the namespace is right in lib/api/api.rb, otherwise, we
might require Grape::API::Helpers which defines the `#params` method.
This is to avoid requiring a file multiple times and getting an "Already
initialized constant" error.
