create a detach helper and use detach helper in replace of nextTick

[seanstrom]

In response to #748

Created a new helper to pick setImmediate when available and process.nextTick when not.
And I then replaced code that relied directly on process.nextTick

+1 but can we call it something else? Maybe callAsync()? detach() sounds like you're detaching the function from somethings. (apologies in advance for the bike shed)

[nylen]

I like callAsync better too. I'm not crazy about either of those names, but I can't think of a better one, so 👍

[FredKSchott]

You could go all Java with setImmedieteOrNextTick()

[nylen]

👎 needs more factories and IAbstractSetImmediateOrNextTickImpl 💩

[emkay]

haha. I've never done any java, but I actually like setImmediteteOrNextTick() the best because it clearly states what it is for. callAsync and detach are somewhat ambiguous, but hey it's just a name.

[seanstrom]

👍 on @emkay's thoughts

[nylen]

setImmediateOrNextTick is fine with me.

[seanstrom]

What about defer as the name.
I spent some time researching what process.nextTick and setImmediate do and came up with that name.
But maybe its still not appropriate.

[nylen]

👍 for defer, I like that best so far.

[FredKSchott]

Woo! 🚲 🏡 complete :)

Sweeet! :) Thanks for this!
