Update scroll-bar when default gloss annotation is updated

[susanodd]

The scroll bar needs to be regenerated once any of the glosses have had the annotations updated in the API.
The scroll bar is only "computed" and is a list of hyperlinks. At the moment, this is only generated again once a new query is done. Otherwise all the "gloss annotations" are encapsulated in it.

This mismatch will only happen if you're actually using Signbank at the same time as things are being updated by calls to the API.
Because the scrollbar is a session variable, it does not update the strings until another query has been done. (By yourself.) So this could be weird for users actually using Signbank while there are API things going on.

I made this happen in a few places in the new views.

The normal update inside of Gloss Edit does not do this yet.
