This branch is an effort to remove a bunch of things from the Blockly wrapper that doesn't strictly need to be there any more. Primarily this includes utils that were assigned to the wrapper instance for convenience during migration, and monkey patches intended to preserve the old Blockly API that was found throughout apps code. No changes in behavior are expected.

As this PR makes changes to a lot of files, it could be helpful to review individual commits. I pushed changes related to single functions together. Each change has been tested locally for regressions.

Follow-up work

Proposed next steps:

• Continue removing wrapper functions. (mainBlockSpace and getWorkspaceCode are good next candidates. They were slightly too big for this branch.)
• Move data stored on the wrapper to a new Blockly data store singleton. (Ex. embeddedWorkspaces, blockLimitMap)
• Move out initialization logic. Decide if it should be standardized like it is now or more per-lab (custom field registration, etc.)
• Delete the wrapper (just that easily)
