Update Dozuki iOS app

1. Fix bugs that showed up as edge cases in the Dozuki iOS app that did not
   appear in the iFixit iOS app.
2. Get rid of Lobster font, replace with helvetica
3. New Feature: We are now displaying Nanosite customers site logo if they have
   provided one. Fallback to text if they do not.

No one merge this just yet, I want to do heavy testing
