Bower Path

I don't think you can actually override `@makerstrap-bower-path` (for importing Bootstrap from a different location) the way things are currently set up.

**makerstrap.less**
```css
@makerstrap-bower-path: '../bower_components';

// Bootstrap base

@import '@{makerstrap-bower-path}/bootstrap/less/bootstrap';
```

We want to make sure people can override (and use mixins from) Makerstrap + Bootstrap without editing them directly.
