Update design [WIP]

[k-nut]

This work in progress branch updates the design to the latest revision. I will keep this comment updated with notable changes

• Use the new beautiful design
• Replace less with sass
• Introduce bower for frontend dependency management
• Remove manual node setup for heroku and user heroku/nodejs buildpack instead
• Remove custom djangocms_pagebanner extension that apparently was not user
• Add new extension that allows including the okfn blog feed (needs to be included on the homepage manually)

To Do

• check all pages (probably forgot to include the new design somewhere)
  • error pages are missing banner
• Fix spacing in right text in banner
• Check for nowdoing statuses in templates
  • Actually display values from database (only after merging Set peoples status through api #294)
• change bower to npm
• Decide how to install frontend dependencies (instead of doing that on the production machine)
• Decide if site navigation should be shown on pages like /network that currently have a custom sidebar
• Add proper links for twitter, facebook and donate in header ( where should they go @morchickit ?)
