Working button - review

Added function using mongoDB to requests.js
Modified issues.jsx giving two functions a button, and some more logic - It had two buttons, a check out and remove, and I decided to use the bgColor itself as a toggle between if it's been checked out or not. Until I get better, this was the most painless to implement.

It appears I committed some changes for the build in a previous commit so those changes can be ignored. Also looks like I added more space to files (hard to keep track of that).

I don't want to commit to heroku until it's been tested/reviewed on your end as I don't know how the mongoDB administration/connection works on heroku and I don't exactly know how to revert those changes either.

It works great in the test environment, but I'm not sure if there are other things I should be considering. One thing is that there always appear to be 5 connections made when connecting to the db/server (believe this is intended though)

-- Checked real quick and looks like MongoLab in sandbox would need to be utilized, we can discuss more about it when we talk.
