Adds 'tags' to gitignore
Adds missing .ruby-version file

README references a missing .ruby-version file, version 2.1.2
Strips whitespace from README.md
Updates database.yml.template instructions
Adds styles to stray submit buttons

Buttons whose stylings needed to be updated were found with the command

    grep -r '\s\s*f\.submit' * | grep -v btn

Which finds all occurences of the text 'f.submit' that don't have the
text 'btn' on the same line.

Minimal testing has been done. All changes were linted, and two actual
pages were tested.
Adds small margin-top to submit buttons

Previously, there was no space between a submit button and the form
element that came before it. As such, a small (15px) margin was added to
the top of these buttons.
