made blockquote font sizes same as regular text

This baby style change makes block quotes have the same font size as
regular text, which is how GitHub styles things as well.

Ref: #172
Fixes sha not being updated when saving to GitHub

Also removed Github.currentName/Github.currentSha as those were not
being used.
