#595 Console should have winnowing Search field

[Nick Kocharhook]

I'm curious if person Xxx has logged on/off in the time I've been
gone. I *could* look through the list of over 100 events logged to
the console to find out if Xxx appears. I *could* copy the whole list
and paste it into Vim. Or, we could add a search field that narrows
down the lines based on a simple match.

I vote for the last one.
