Minor log edit

Update deltabot.py
Required arguments mismatch

points_already_awarded_to_ancestor requires 3 arguments (self, comment,
parent). It was only given 2. I have added awardees_comment in hopes
that it will correct this issue.
Required arguments mismatch #2
Mismatch #3!
Added history auto-clear

Added "reset_counter" to the go(self): function. This will count to 10.
When it reaches 10, it will clear the comment history and perform a full
scan of the comments. This is a temporary solution to alleviate missed
deltas that we've been seeing lately. A better history feature will
properly solve this issue.
Added confirmation to deltabot add command
