Merge pull request matthiasmullie#62 from EkkoSense/master

Allow URL-rewriting without saving the minified content to the file system

Don't collapse line feeds after "return"

return is not guaranteed to be followed by a return value.
It could just be "return", followed by nothing (void return),

We may just need ASI to kick in there, so keep the line feed
after return.

Don't convert standalone arrays

"return" looks like it could be a variable of which ['x']
is a key. I've improved the code to also check for keywords.
If whatever preceeds it is one of the keywords, don't convert.
