Upgrade YUI Version inside AlloyUI

• Take a note of YUI version set on alloy.json dependencies.
• Navigate to [ALLOY_ROOT]/../yui3
• Fetch the a pure copy of the used version of YUI, in this case v3.11.0:
  • git fetch https://github.com/yui/yui3.git v3.11.0:v3.11.0
• Fetch and checkout the latest YUI tag v3.15.0:
  • git fetch https://github.com/yui/yui3.git v3.15.0:patched-v3.15.0
  • git checkout patched-v3.15.0
• Generate the list of commits that differs between the current YUI version and AlloyUI patched branch, in this case v3.11.0 and patched-v3.11.0:
  • git log --oneline --reverse v3.11.0..patched-v3.11.0
  • Let's assume the log difference outputed:
    • 62757e6 Commit 2
    • 62c3ac4 Commit 1
• Based on the list of different commits run:
  • git cherry-pick --allow-empty --strategy=recursive -X theirs 62757e6 62c3ac4
  • Resolve all the cherry-pick possible conflicts, you may need to run git cherry-pick --continue several times.
• Once the commits are cherry-pick sucessfully, lower your node version to at most v0.11.13, since yui grunt tasks don't work with newer versions.
• Now build and test all modules:
  • npm install
  • grunt build
  • grunt import-pure
  • grunt test
• If all test are passed commit the built files:
  • git add . && git commit -m "Build files"
• And push the new branch to liferay/yui3 repository:
  • git push upstream patched-v3.15.0
• Update [ALLOY_ROOT]/bower.json "dependencies" to use the new patched-v3.15.0 branch.
• Update [ALLOY_ROOT]/alloy.json "yuiversion" to patched-v3.15.0
• Rebuild AllloyUI from [ALLOY_ROOT] folder:
  • gulp build
  • gulp test
