Disable staff markup on 'detached' blocks.

First pass at an API for XBlock testing.

Remove Pylint violations

Fix: Disable capa buttons to protect against race condition that may occur between two competing AJAX calls.

[SWAT-97] Logistration alignment and padding.

Staff markup was enabled on all block types in
https://github.com/edx/edx-platform/pull/10903

This works well inside the courseware, but it breaks layout of the course about
page, which is also an XModule, see:
https://github.com/edx/edx-platform/pull/10903#issuecomment-164266342

This commit disables staff markup/staff debug on all blocks except
blocks tagged with 'detached'. Detached blocks include course about
and info pages, static tabs.

Append block item only if it has path to root

WIP for financial support tool.

Allows support staff or global staff to view a list of a learner's
enrollments, and change enrollment modes. We generate a
ManualEnrollmentAudit record for these enrollment changes in order to
track updates. Additionally, enrollment changes are handled through
the enrollment API, which handles bookkeeping such as granting refunds
where appropriate.
