Add a auto-beautifier for Podfiles

[orta]

Idea: CocoaPods.app could handle your indentation, etc

This is useful in general, cause its less to think about. However, this is extra useful when using auto-complete which currently doesn't take tab indentation into account.

Implementation:

• We could install ruby-beautify into our hosted environment via the Rakefile, this is probably preferable to using rubocop (due to less dependencies, but open to discussion there )
• We could then run this before every save
• It should be on by default, then provide a menu item under "Editor" in order to toggle it off/on
• indent via 2 spaces

Example

When running it on Artsy's Eigen:

~/d/i/a/eigen (master) ⏛  ruby-beautify Podfile -s -c 2

diff --git a/Podfile b/Podfile
index 1223224..29a5663 100644

If possible I'd prefer to use rubocop since that's what we use across all the different CocoaPods projects
