[#76] Downgrading simplecov due to rspec/capybara/etc issues under Ruby2
[Finishes #76] Massaging time zones so specs can pass.

Expectation is that all times are PST (or whatever the rails app is
configured for) as of right now. Code to adjust time zones in the view
and controller has been disabled (view change only) as its effects were
not accounted for fully.
