ECOM-4272 Add the cosmetic changes to the program listing page

Sequence navigation UI events.

seq_next, seq_prev, and seq_goto events are all renamed, and maintain
legacy compatibility.

This PR also introduces new EventTransformer framework to shim events
based on name prefix.

SUST-40 – Eliminate unwanted problem_get ajax requests flooding the LMS.

ECOM-4101

An event is being fired on actions (Check/Save/Reset) to keep track of updated problems. On coming back to already visited sequence position, while putting sequence contents in container, only those problems that are found outdated, are going to be updated from earlier tracked problems.

[SUST-40]

The page visit requires an ajax request to get the notes. Without
waiting for that to complete, additional navigation results in a
socket error.

Example failure from the stub service:

Use type_in_codemirror instead of ActionChain to set content.
