Framegrab does not attach to multiple annotations at the same elapsed time #77

Replicate VARS function: When you create a frame grab and do not advance the video, multiple annotations should be attached to the same frame grab.

Got it. Here's what's going on - for my notes.

The framegrab is attached to multiple annotations. However, only the one created is updated in the UI, the others at the same time need to be refreshed and re-read from the annotation server. Need to add code to recognize the related annotations, fetch them, remove the existing ones and replace them with the udpated ones.

IMPORTANT Major testing of framecapture required after rework!!!

Verified the framegrabs get attached to the all annotations with the exact same elapsed time index. However, I've noted that even when you seek to a point in the video and then take a framegrab their may be some offset in the 10s of microseconds so the the framegrab annotation may be offset from the annotation that was seeked to.
