v0.7.0

Removed Content Security Policy violations from https://github.com/facebook/regenerator/blob/master/runtime.js due to the use of the Function constructor as an indirect eval mechanism (#112).

This change has the potential for backwards incompatibility if you are using a minifier that does not preserve the name of the GeneratorFunction constructor. To work around this problem, either consider using https://github.com/facebook/regenerator/blob/master/runtime.js unminified, or find a way to tell you minifier not to mangle the GeneratorFunction name. If this extra burden is super annoying, please file an issue letting me know.
