Add new outputDir option

[denar90]

Hi @HollandBen. I was thinking about adding new option(s) for this task.
I propose to add outputDir option - a directory for placing hashed copies of files. It will be the same as assets but developer can specify it.
Another option clearOutputDir which will clear dir with copied hashes. Default value of it might be false. If outputDir was not set it can't be true.
Is it worthwhile?

Yeah, that would work well I think 👍

Yeah that would be very helpful!

Currently I have issues with git, as I can't ignore the renamed files, how do you handle it? I now that using something like '..js' in gitignore would do, but it's not so nice
