Use external package to flatten an array in utils

[dee-kap]

Move the code which flattens an array to an external package. That's it for this simple change.

Thanks, though can you change it to use the array-flatten module instead, since that's what we use in the router module?

[dee-kap]

I don't see array-flatten being used anywhere.

@dougwilson I have replaced arr-util with array-flatten.

[dougwilson]

array-flatten is missing from package.json

[dee-kap]

What would be the best way to push this fix through?

[dougwilson]

Typically you would just add it to your package.json and just push a new commit to the branch that this PR came from :)

[dougwilson]

Actually, nevermind, looks like I already merged this commit into the 4.13 branch :) Looks like you need take no action at all :D

Thanks.
