Bunch of changes to decrease false positives and update dictionaries.

Fairly extensive updates to the dictionaries to:
- update some frequently covered countries for leadership changes in the last few years
- improve actor accuracy by tweaking actor and agent files
- reduce miscodings (specifically 190s) by changing the verb file.
- dramatically ramp up the ruthlessness of the discard list
- make assorted changes based on the first version of the Phoenix data
