Release History should be paginated

[miketheman]

The history part is a JavaScript-enabled tab, not a real page today.

Projects that have long lists of releases are really long, and can get unwieldy.
Example: https://pypi.org/project/botocore/#history

When loading the page, we query for all_versions and then render those into the HTML.

	.filter(Release.project == self)
	.order_by(Release._pypi_ordering.desc())
	.all()
	)
