Generate more unique project filenames when list isn't a github org #71
Description
For project lists other than github orgs, it's possible to have multiple projects with the same repo name
One such example exists under Hack for LA currently:
Even worse in this case, it's two different casings for the same word which wrecks havoc in case-incentive environments like Macs
The crawler should, for project list types that aren't org, generate filenames in the for ${organization}--${repository} to ensure uniqueness. Rolling this out would generate a massive set of renames though that could break historical analysis. Maybe this expanded naming could be applied only when collisions are detected instead to minimize historical churn?
