Sync up with YUI.Test

[caridy]

WIP / PROTOTYPE / EXPERIMENT

For some reason, this repo, and the this package got stale compared with the code in yui/src/test, this PR is suppose to get them align, and finally help to remove the code from YUI Library, making yuitest is truly stand alone project.

When looking at the diff, make sure you use ?w=1 otherwise the indentation (whitespaces) are going to mess with the diff:

https://github.com/yui/yuitest/pull/26/files?w=1

According to the YUI History File for test module, this is what has changed:

3.15.0
------

* Added test.next(fn) which returns a callback that automatically
  resumes asynchronous tests.

3.14.0
------

* Added Y.ArrayAssert.isUnique()

3.11.0
------

* Modified YUITest.hasNoKeys() to bypass Android 2.3.x prototype
  enumeration bug. (GH #949)

@caridy with this we can make PR here or in YUI/src/test?like the PR we made today #25 ?

[caridy]

@ctadeu ideally we will have all upcoming PRs against this repo, but it might take some time to get this merged. As today, the copy of the code from YUI into this repo is automagic, so if you get your PR merged in YUI, we will get it here as well, but again, I don't have a specific timeline with this refactor.

Ok, perfect, will submit the PR in YUI, thanks man!

I actually wrote this one and contributed it to YUI where Lang and Array are available. I'm concerned that the following calls might break:

• Y.Lang.isArray()
• Y.Lang.isValue()
• Y.Array.isUnique()

Could that happen?

[customcommander]

I just made a PR to your branch to remove those dependencies.

@caridy, I'm very keen on seeing this going forward. Before I saw this PR yesterday I started to do some housecleaning (jshint & yuidoc fixes, whitespaces and indentation cleaning) before doing anything major.

Do you see this as a waste of time/not big priority or complementary? Ideally I'd like to sync my efforts with yours but I'm totally fine with doing the small bits if that's the way to go.

[customcommander]

@caridy I've made several PRs against caridy/yuitest to complement this one. Have you got any comments on those? Would you rather see them merged into one instead?

[caridy]

@customcommander, I'm on the road for two weeks, I will try to get a chance to work on this at some point, but it will take some time.
