Updated Rails version.
Revert "Updated Rails version."

This reverts commit 2b536a0c0c4eded1178bb3f278f3e2871c0afcf4.
Initial User Profile model implementation.
Updated rack-mini-profiler so it is "hidden" to start.
Refactored Account::Users controller to serve as the defacto "account" resource.
Updated permissions to include accounts/profiles.
Initial resources for Accounts::Profiles.

The views are all stock and need refactored.
Updated generated Profile views.

This is still mainly a WIP. Since the profile form will necessarily touch at least two models, I'm leaning toward refactoring to use a Form Object.
