Update more than once a day

[stueker@…]

Idea:

I wondered why the script can only be started once a day. There may / should be progress visible over the day. I inspected the script and found that the only reason was the SQL-Insert-command which cannot be run twice. Instead an SQL-Update-command is needed.

Solution:

Changed the burndown_job.py script to update the burndown table when called more than once a day.

Enhanced burndown_job.py

I think a change for updating multiple times a day is fine. I originally only did once per day because on my team, developers did not want to change estimates multiple times in a day. We found one a day to be sufficient. I will post this change to the main page within the week.

I'll probably change the variable name from 'mode' to 'needs_update' or something to make it more clear. But otherwise I'll use it as is.

Thanks.
