Don't let blame run for longer than 15 seconds

Browse source 
Summary: Fixes T2450. If we spend more than 15 seconds in blame, just cut it off.

Test Plan:
  - Changed timeout to 0.01 seconds.
  - Did blame on a non-highlighted file, got no blame, saw warning.
  - Did blame on a highlighted file, got no blame.
    - Note: you don't get a warning here because of Ajax stuff. It'd be kind of tricky to add and doesn't seem like a big deal so I'm planning to leave it as-is for now.
