Improve internal linking and browsability through crowd-sourcing missing data

[dracos]

There are two main examples of weaknesses in our data that could be improved by crowdsourcing certain gaps in our data:

• Hansard backreferences (e.g. the reference to a previous Hansard on pages like http://www.theyworkforyou.com/wrans/?id=2006-06-12b.75897.h ). Rather than linking somewhat unhelpfully to the column, we could build a tool to enable volunteers to pick the correct result from the column, and then we could stud Hansard with links to the exact right place.
• Things that are deposited in the library of the House - all listed on http://deposits.parliament.uk/ in a big long list - could be linked directly to the document to which they're referring. Use references to MP names in order to speed this up for letters, and see https://secure.mysociety.org/cvstrac/tktview?tn=923,31 for a ruby scraper.
