Redesign and implement header bar

[Bad-Science]

We have a new design for the header bar that needs to be implemented.

Since we are transitioning over to bootstrap, bootstrap should be used for the layout, and the header should be responsive. i.e. it should display properly on a mobile screen or a screen of any size (the current header wraps if the screen is too small and looks bad).

The current iteration of the header design is as such:

I think the design (of the header) needs a little more refining though

Thanks @esoterum and @wzq97 for the help with this!

Going to knock this out this afternoon, along with #26 . Will likely submit one PR for the two of them.
