Description
Some of our files - especially the views - have trailing white space or are missing EOF lines.

Ask
Fix annoying white space issues

To Do

• Make sure any view that is missing an end-of-file line gets one.
• Remove all trailing white space from every view.

Additional Info
Please only make white space changes when making this pull request. If you set up your editor with proper settings, this may only mean opening and closing every view. 👍

I opened and closed every file in app/views with my Sublime user settings set to include

"translate_tabs_to_spaces": true,
"trim_trailing_white_space_on_save": true
