[v1.0.0-beta.2] cacheKey doesn't take uglifyOptions into account

[mikesherov]

The cache key for cached version of the output should also include the options passed to uglify, otherwise, the same input with different options will yeild incorrect output.

@mikesherov What solution do u recommend? Maybe include [chunkhash] or [hash]?

[mikesherov]

No, I recommend stringifying the uglifyOptions as part of the cacheKey generation at the same spot uglify version number is appended.
