This:
1. Introduces a variable for the Course Outline view in Studio.
A custom theme can override it to add new editors.
2. Exports a function for creating new editor modals.
A custom theme can use it to create editors without adding boilerplate code.
3. Adds a pluggable override for XBlock fields that are passed to the Studio.
Without this, custom editors in Studio cannot retrieve values of XBlock fields.
This:
1. Introduces a new override using the `pluggable_override` decorator.
It is now possible to specify a custom way of getting XBlock's icon
by defining `GET_UNIT_ICON_IMPL` in settings.
2. Introduces a way to add custom `XBLOCK_MIXINS` by defining
`XBLOCK_EXTRA_MIXINS` in settings. This allows, e.g. to add
new fields to XBlocks.

* Minimum possible changes were made to merge CapaModule & CapaDescriptor into
one ProblemBlock class.
* There are no known changes in behavior.
* CapaModule and CapaDescriptor inherited from a number of classes which inherit
from XModule or XModuleDescriptor but did not depend on them. For all these
classes the methods were moved to mixins which did not inherit from either and
then these mixins were added to ProblemBlock in the order which maintains MRO.
Before this commit, XBlock static assets were extracted during the
collectstatic process by iterating through all installed XBlock classes
and creating a separate directory for each. However, some packages
install many XBlocks that actually share the same static assets. The
most notable example is problem_builder, though we also see this with
schoolyourself and google_drive.
This commit uses the parent module name to do package asset lookup,
collapsing those cases down and eliminating duplicates. For a default
install of edx-platform XBlocks, this reduces assets generated from 31M
to 14M.
