The d3.js library is now added and the quota infographics
have been redone to use d3.
Added a reusable animated d3 pie chart that is now used to
display the quota infographics.
Reworked the progress bars (horizon.quota.js) so that project
quotas when creating a new Instance / Volume display a progress bar
in D3. Also changed progress bar for adding a floating ip so that
it shows that 1 will be used up on create just like adding a new volume.
