Behold a global spinner

Created a spinner component with an absolute position. Can use separately or call the global instance. Can also use the spinner "react-spinner" by itself if desired.
Right now, only shows the spinner without altering the background

I think the "short styles" should still be within the `components/index` file and leave this a one-liner.
