Explain how local dashboard gets issues (#20).
Expose JSON data dump of all PR info

Example: /all-prs.json?offset=0

PRs are returned in ascending order by number.

Can only fetch info on 100 PRs at a time in order
to avoid OOMs; users must manually alter the
offset to perform paging.
Display comments left on code diffs (fixes #8).
Support pagination when fetching comments and changed files.

Prior to this change, we would display outdated comments for PRs
with very long discussion threads.
Move Flask app creation to __init__.py.

This will make it easier to access the app's configuration from

This is intended to replace https://github.com/pwendell/spark/blob/github-integration/dev/github_jira_sync.py when we move to the new Jenkins.
Compress large JSON properties.
Add page to list all open pull requests.
