[PERF-303] Integer XBlocks/XModules into the static asset pipeline.
This PR, based on hackathon work from Christina/Andy, implements a way to discover all installed XBlocks and XModules and to enumerate their public assets, then pulling them in during the collectstatic phase and hashing them. In turn, the methods for generating URLs to resources will then returned the hashed name for assets, allowing them to be served from nginx/CDNs, and cached heavily.

- Ensure that only a course import is saved to the draft branch and then
published. A content library has only a single 'library' branch.
- Add a fields parameter to the create_library call so the call has the
correct number of parameters.
- Add tests which import content libraries using different test methods
and with different branch settings.
- Add test which imports a content library and then exports it.
- Use XBlock module version that supports XML-serialized String of None.
- Add re-import of content library and equality comparison to test.
- Allow get_items to be called on LibraryLocators.
- adaptation asides to be imported from the XML
- updating SplitMongo to handle XBlockAsides (CRUD operations)
- updating Studio to handle XBlockAsides handler calls
- updating xblock/core.js to properly init XBlockAsides JavaScript
