change fakehub to make dogfooding of sourcegraph easier
Created by: ijt
Fakehub can now be run on a directory containing git subdirectories and it will serve them all.
Test plan:
cd dev/fakehub; go get
fakehub <some directory containing github repos>
- Open the url it prints out, click the config link, paste the config into a local sourcegraph instance, try it out.
