Bored thanksgiving angularjs rewrite

I was bored one night when my family all went to sleep at like 11 PM and I wanted to work on something small-ish. So I thought "I'll add the ability to do multi-line quotes in the quote board" since there have been situations where I wanted to do that. However, I decided that it would be easier for me to do that if I rewrote the frontend in Angular and got rid of jQuery altogether. Turns out it wasn't so small after all.

# What's new
* Rewritten in Angular
* jQuery has been banished
* Animations are CSS transitions
* Keyboard shortcuts added:
    * `ctrl + n`: show new quote pane
    * `esc`: hide new quote pane
    * left/right arrow: previous/next quote
* Ability to add more than one line to a quote

Here is the creation pane for a single-line quote

and a multi-line quote.

Here is how I have the board looking now with a single quote

and a multiple-line quote.

Sorry, I know this is a crazy huge pull request. 
I planned to add some karma tests too but it got too late and I had Black Friday shopping the next day.
