Refactoring and tidying Rickshaw code. Placeholder graphs inserted. Front page sparklines are sensibly sorted.

Added modified version of the JQuery sparkline library.

Implements downloads counts (for dataset resources) and fixes an issue with 'All' records.

- Fetches the data for downloads (either direct or cached) from when a user clicked on a
Download button. We lookup the resource for this url (based on .url or .cache_url) and
then associate the download count with the package it belongs to.
- Fixes a bug (#211) where the All records are deleted for every url, even if that url was
not fetched (and therefore won't get a new All record).

Only show the months for Downloads that we have
