Bring back initPolymer, allow boot.js only if using "polymer_experimental.html".

Q: I wonder if I should just move the code that is left in boot.dart here. I
kept it there to make the review simpler too.

[Jennifer Messerly, 2014/05/23 07:20:06]

I guess the main reason is if you want it to be public? Otherwise I would move
it here.

[Siggi Cherem (dart-lang), 2014/05/23 17:56:33]

Done. Moved it here. At least now it is structured in a way that it can be
imported more easily if we rewrite the boot.js as boot.dart in the future.
