bfg to make repo smaller

[jpmckinney]

This repo was 300MB+ to download, despite now containing hardly any data, due to previously storing real data. To make it easier to work with I ran:

bfg --strip-blobs-bigger-than 1M .
git reflog expire --expire=now --all; and git gc --prune=now --aggressive
git push --force origin master

I've attached the list of deleted files.
