Improve the custom build of Aloha Editor

As documented in the custom Aloha Editor build profile that is included with the module.

We would have to ensure that our duplication of AE's dependency tree in our hook_library() (D7, D8: hook_library_info()) implementation is sufficient to allow us to load all of Aloha Editor without using require.js at all.

The AE guys have realized that their build system and their use of require.js is rather painful and complicated, so they're working on improving this: https://github.com/alohaeditor/Aloha-Editor/issues/737
