Roll back google-apis-core for code-dot-org compatibility

[cat5inthecradle]

As part of the 0.2.1 upgrade (#7), I also updated and pinned google-apis-core to the latest version, 0.15.1. This has a dependency of googleauth 1.9. However, over in the code-dot-org repository where we use this gem, we also use the old google_drive gem which requires googleauth < 1.0

This PR creates version 0.2.2 and rolls google-apis-core back to 0.11.3, the most recent version compatible with googleauth < 1.0

LGTM!

Confirmed that all dependencies resolve as desired when installing directly from github:
