WebBasket: adjustments for Twitter Bootstrap usage
- Adds content to Your Account/Baskets widget (dropdown list of baskets, link to /yourbaskets)
- Implements 'add to basket' in search view
- Replaces broken layouts in html with bootstrap classes The old html is not replaced where it looks OK. If we want to fix it completely, a Jinja template should be added instead of editing the old style html generator.
- Replaces images with bootstrap icons (the wb-* images are not removed from system in case they are used somewhere else).
- Removes unused imports.
