* [License] Simplify the Texture license to be pure Apache 2 (removing ASDK-Licenses) With permission of the Facebook Open Source team, we are simplifying the Texture license so that clients can rely on the Apache 2 terms that most of Texture is already covered by. This means that code originally forked from AsyncDisplayKit will be re-licensed from "BSD 3-clause + PATENTS v2" to Apache 2 without a PATENTS file. After getting confirmation that the updates to these core files look good, we'll propagate this new license header to all files (in this same PR) and get sign-off from all parties before landing. * [License] Update all Texture source files to be pure Apache 2. * Changelog entry for Apache 2 license update. * Revert "[License] Update all Texture source files to be pure Apache 2." This reverts commit ffa0fbbba9717d871dd16c4b07539f2f8208fc2b. * [License] Update all Texture source files to be pure Apache 2, maintaining copyrights. * [License] Update CONTRIBUTING, README, Podspec & Dangerfile.
