Display automated analysis fields in UI

[Mr0grog]

The new automated analysis process creates annotations with a number of fields:

• priority
• source_diff_hash
• source_diff_length
• source_diff_count
• source_diff_ratio
• text_diff_hash
• text_diff_length
• text_diff_count
• text_diff_ratio
• links_diff_hash
• links_diff_count
• links_diff_ratio
• (soon to come) something about watch words: Increase priority for special terms in automated analysis web-monitoring-db#416

We should figure out which (if any) of these we should show in the UI and how.
