Change maven dependencies to compile against SDK 4.3_r1 (API 18).

Add Sergei to .pairs
Robolectric is now compiled against 4.3_r2.

You can switch which version of the SDK a test is run against by
specifying @Config(emulateSdk = [16|18]).
Don't redirect build output (it was accidentally included in the bundle).
Added support for running tests with API 17.
Merge pull request #735 from mag/upgrade-android-jars
