Feature/update ui bootstrap modals

@ByronDarlison @tejohnso These are changes to style-guide I made. I added a Modal page that basically copied the ui-bootstrap example of how to create modals.  This pull request will eventually include all the changes once the common-header and component-storage-loader repo is updated.  This repo will be merged last.  Let me know what you think and when It looks good to go.  There are some small minor bugs I fixed too while doing this on this branch.
