Add a settings page

[ismail-s]

Need to be able to change blog title, theme.

• Create db wrapper that presents settings db table as dict
• Create mapping listing all settings that can be changed
• Add more options to mapping to specify min/max directly there
• Create route and view for displaying settings page
• Create template for settings page
• Handle submission of changed settings
• Upon startup, make sure all settings exist, requesting from command line any that don't
• Change settings usage in rest of web app to use settings dict
• Make sure both templates work
• Remove unnecessary settings in ini files
• Make sure all settings we want in settings webpage are in settings webpage
  • Add fireblog.recaptcha-secret setting
  • Add fireblog.theme setting
  • Add Persona settings
• Remove any redundant code
• Tests...

So far, I've added a settings class thing which abstracts the db away, presenting a dict interface. The class also has caching.

The main thing remaining now is to update the tests, and add tests for the settings page.

Existing tests have been fixed, just need to add new tests and remove redundant code.
