Video player seek issue

Fix display of all words in word clouds.

Update sailthru audit purchase calls

 The embedded video player does not allow the screen reader user to seek forwards / backwards within the time with the keyboard as you could in the past. If you tab to play a video and press spacebar or enter, you formerly would be able to press left / right arrow to move slightly forward or backward in time, but this no longer works correctly; it will move 1 second back / forward, then you need to press tab again to refocus and move another 1 second. Other keyboard access seems to be equivalent and we suspect a slight error in the Javascript is causing this and needs to be fixed.

EDUCATOR-3034

Update token expiration for DOT tokens

When notifying credentials of cert/grade changes using
notify_credentials, don't worry about signaling for program cert
awards. (A) We don't need that functionality right now when
backpopulating credentials records, and (B) we have other management
commands for that anyway.

This will retire a refresh token and access token pair in the DOT tables
if the access token is 6 months expired (prior to that, the refresh
token still works).
