Cirq v0.9.1 release

[Bálint Pató]

Dear Cirq Users,

We noticed an issue with yesterday's v0.9.0 release and fixed it quickly to ensure a smooth upgrade, and released it as the v0.9.1. hotfix release. 

Cirq v0.9.1 is available via pypi, pip install cirq=0.9.1 or on our Github release page.

This point release fixes the renaming of cirq.TrialResult to cirq.Result in a backward compatible way with regards to the JSON parsing as well. There are no changes in any other user-facing functionality.

No other changes to cirq functionality. No protocol changes, top-level changes or other changes.
