Various refactoring and maintenance edits

*Features:*
- Built a basic static pages controller using blank layout for now.
- Added FAQ as example of a static pages view in action
- Added [foreman](https://github.com/ddollar/foreman) to gem list, create initial Procfile (start it with `foreman start`)
  - This should allow us to add redis and create scheduled jobs (like sending digest emails for quicklove?) in the future with minimal pain

*Fixes:*
- Rubygems.org yanked crypt3, so source the gem from github/rubyunworks
- Removed trailing whitespace throughout the project.
