[Conference Submission] Pressing 'return' adds tag

[TomHeatwole]

When you are typing inside the any of the input textboxes, pressing 'return' adds a tag.

I've come to realize that this problem is weirdly specific. Once the tag-picker is fully functional with ember-osf, then the tag-picker will usually be blank. Entering a tag will remove the text in the tag. The only way to reproduce this bug will be to type in the input field for the tag without adding it, then go back to the title or contributors field (which should have already been filled out), then press the 'return' key. While this is an error that we should probably eventually pick up, I don't feel like it's high priority right now.

Adding an action to the textfields doesn't prevent them from adding the tag. Input fields automatically look for the next button and run that. Preventing them from adding them may be possible with jquery as seen here: http://stackoverflow.com/questions/6675718/how-can-i-prevent-the-enter-keypress-from-triggering-a-button-click but figuring out exactly where to put the jquery could still be challenging.
