Perf tests for Plugin Power Saver take 2.

Perf tests for Plugin Power Saver take 2.

This time, with more throttled plugins!

I'm adding 2 different benchmarks:
1) some popular sites that have throttled foreground plugins
2) a control site that we should also do well on

and creating tests that will run both benchmarks with and without PPS.

The class-level pydoc for these each benchmark will show up on the perf
dashboard as documentation for anyone looking at the graph. Might be worth
explaining:

1) What pps stands for
2) What is in the page sets (what does PluginPowerSaverPageSet test, what does
ThrottledPluginsPageSet test)

Looks like this had up to about a 15-20% impact depending on the platform, which
is pretty encouraging. Thanks for putting this together!
