angular/angular.js

Currently there is only a minimal test spec in place. But this will now
be run as part of the test tasks.

…ue a reflow

Closes #4278
Closes #4225

Forward SauceConnect logs and Karma debug logs into a file and print these files at the very end of a build.

This target was never un on our Jenkins CI. Some of the specs are using animation stuff, that IE does not support, so I'm disabling them.

BREAKING CHANGE: since all the code in the ngMobile module is touch related,
we are renaming the module to ngTouch.

To migrate, please replace all references to "ngMobile" with "ngTouch" and
"angular-mobile.js" to "angular-touch.js".

Closes #3526

- ngAnimate directive is gone and was replaced with class based animations/transitions
- support for triggering animations on css class additions and removals
- done callback was added to all animation apis
- $animation and $animator where merged into a single $animate service with api:
  - $animate.enter(element, parent, after, done);
  - $animate.leave(element, done);
  - $animate.move(element, parent, after, done);
  - $animate.addClass(element, className, done);
  - $animate.removeClass(element, className, done);

BREAKING CHANGE: too many things changed, we'll write up a separate doc with migration instructions

This should not affect the Jenkins build at all.

Now, the Travis build uses Chrome on Sauce Labs, which in theory gives us opportunity to use any
browser/platform that Sauce Labs offers.

And also add shared config to make karma configs a bit simpler.
