Remove Babushka::IP, which is unused (it's at http://github.com/benhoskings/ip).
Remove #get_path helper (vars used it, but Babushka::Prompt doesn't).
Indentation in prompt_spec.
Replace Prompt::Helpers with methods in DepDefiner.
Call LogHelpers directly instead of extending Prompt with it.
Make Babushka::Prompt a module instead of a de-facto singleton class.
Brackets.
Update the bundle (only affects testing).
Add a special source name: "common" -> benhoskings/common-babushka-deps.

This source will be used for very widely applicable deps, for things like
deploying, remote running, and so on. The exception is there to allow the
"common" repo to live in my github account; otherwise, I'd have to manage
a separate github account for it (and find a good name for the repo whose
github account is still available).
v0.16.10 - Added a 'common:dep' source, refactored some modules away, and removed some old, unused classes.
