Optimizely integration throwing a JS error in IE7

We're getting JS errors, from IE7 only, originating from the analytics.js library. It looks like Optimizely.prototype.replay trying to call window.optimizely.data.state.variationNamesMap, but state in that call chain is undefined. Since Optimizely no longer supports IE7 as of Oct '14, I'm assuming the Optimizely object state is being partially initialized.

I'm happy to do a PR with a simple null check on state (in addition to the null check on data), but I wonder if you guys have any better ideas?

(Also, not sure if you guys are supporting IE7 - can't find the browser support info.)
