Lots of major styling changes here. Pull it in and take a look!
Don't forgot to update your bootstrap version (npm install). Also you will have to use the branch of BPL where I've updated bootstrap (https://github.com/Blocp/bpl/pull/24) or make all of the changes in that PR inside the node_modules/bpl folder of your local buildings install
