Code Drop WIP: Default reviewers with conditions
code drop for Saturday 27th. Little later than 24 hrs before the 

meeting but its here. 
I spent the time I had tracing my way to find how

admin/db/reviews/defaultreviewer/add is defined. Regex didn't help

much at first until I read up on Django project structure.
So far, this patch adds the conditions field to the

ADD DEFAULT REVIEWER page but there is no default values yet. 

This means hitting plus doesn't do anything. I've got a few ideas but

if I can't find anything by tomorrow I'll ping someone in slack.
Next week my school schedule will be less irregular so I hope to get

something working by next code drop.
