Update Link to v1.4?

Sure! Please make the patch to the .make file and I'll kick off a test build on Travis. That plus some manual testing should be enough :-)

Moving to Panopoly Core component for our test script

Here's the test build on Travis CI:

Thanks! Here's the new test build:

There is some discussion in #2666912: URL validation rejects existing valid content after upgrade to 7.x-1.4 and #2651742: always Not A Valid URL about Link's new validation layer breaking backwards compatibility. Certain links that were passed as valid in 1.3 now fail validation in 1.4. The problems include links in multilingual sites that go from one language to another, and internal links that are served by a system other than Drupal that's used on the same domain.

@cboyden: Thanks for the intell! This probably means we either wait until the upstream community works it out, or we could include a patch that reverts the validation change (as opposed to "fixing" it, which could mutate before being committed upstream).

The patch in https://www.drupal.org/node/2666912#comment-11204309 does exactly that: reverts only the validation change.

Unfortunately, it looks like this problem wasn't fixed upstream. In fact, there have been no commits since the 1.4 release which was over a year ago. :-/ So, it seems like updating to 1.4 with the patch to revert the problematic feature is the best solution!

Here's a patch

EDIT: And here's a new Travis build: https://travis-ci.org/panopoly/panopoly/builds/232588906

Here's a new Travis build after some attempts to fix the tests:

https://travis-ci.org/panopoly/panopoly/builds/235004330

The tests pass, and this looks good to me. Thanks, Everyone!
