6 year date selection

[noahmanger]

This makes several changes to the front-end to support 6 years of schedule A and B data at a time.

• Adds a new macro for a date validation filter, which requires https://github.com/18F/fec-style/pull/759 . This filter checks that the years entered are within 6 years of each other.
• Updates links from candidate, committee and election pages to pass through min and max dates, rather than the two year transaction period
• On candidate pages, when looking at a full 4 or 6 year period, the full date range is passed through in links to the itemized data

This also includes a fix so that other spending aggregates on candidate page link to the full 4 or 6 year time period for IEs, ECs, and CCs (resolves https://github.com/18F/openFEC-web-app/issues/2133).

Closing this in favor of work in https://github.com/18F/fec-cms/issues/1371 which will use the work started here, but will need to be refactored to work in the fec-cms repo
