fixed a weird variable expansion
we more or less have a settings page. doesn't WORK though.
rails g scaffold Comment
Added associations and tested them
Added hidden TOS field to edit settings page so it works
Settings form now works (and is prettified)

Had to add some Devise crud based on advice on their wiki, otherwise
you couldn't change your settings without changing your password.

Also had to make a hidden field for tos_agreement. I don't really love
it but nobody seems to be able to recommend a better way.
s/Log in/Sign in/ -- be consistent with devise
oops, broke tests with the change to 'Sign in'
Wrote some very basic tests for the improved settings page
add show_email field to members
Merge pull request #103 from Skud/edit_settings

Attempted rearranging settings page, broke something
