Add support for PhantomJS 2.0

[habdelra]

For our build environment we want to start using PhantomJS 2.0 to address stability problems we are encountering with PhantomJS 1.9.7 randomly crashing. Currently only phantomjs 1.9.7 is available in the build environment. Building phantomjs manually as part of our build is not feasible as it requires us running apt-get for the necessarily dependencies, and the build takes multiple hours to run in order to compile phantom JS.

It would be great if the PhantomJS 2.0 binary was available in the build environment. I think it would make sense to have multiple ver of phantomjs available, where we could set a property in our .travis.yml to select the version we want to use.

thanks!

We should have PhantomJS 1.9.8 at the moment. What breaking changes does 2.0 bring?

[msridhar]

@BanzaiMan see the release notes; removal of CoffeeScript support is one breaking change listed there. A big plus for 2.0 is that it is based on a much more recent version of WebKit, which I imagine makes it applicable in more scenarios.

There is no official binary available yet. (ariya/phantomjs#12948) The process is a major resource hog, and it is not feasible to compile it on the fly. If it's still not available for the next update (1st week of April), we can compile a binary separately for our purposes.

For those brave souls who want to try PhantomJS 2.0.0 now, you can use https://s3.amazonaws.com/travis-phantomjs/phantomjs-2.0.0-ubuntu-12.04.tar.bz2. The archive expands to the binary phantomjs for Ubuntu 12.04 64-bit, and the license file to comply with PhantomJS's BSD license.

PhantomJS fails many tests that pass on PhantomJS 1.9.8 for me, due to the reasons outlined in teampoltergeist/poltergeist#574 / ariya/phantomjs#12506 / teampoltergeist/poltergeist#585

File upload doesn't seem to work consistently.

[BanzaiMan]

@parndt In a way, then, these are expected failures with PhantomJS 2.0.0, correct?

[parndt]

@BanzaiMan yes, I'm just vocalising objection to upgrading the default version until they're worked out.

[BanzaiMan]

@parndt Got it. I'm leaning towards offering both 1.9.8 and 2.0.0.
