simplify number of options for comment period?

[Glen Mazza]

Hi team, on the blog entry edit page, I sense we offer more options in 
our "Allow Comments [for number of days]" dropdown than are necessary 
for most business cases. I'd like to make that dropdown shorter and more 
week- and month-centric.  Instead of these options:

1,2,3,4,5,7,10,20,30,60,90,unlimited
I'd like to switch to these:
3,7,14,30,60,90,unlimited

I.e., 3-day short comment period, 1 week, 2 weeks, 1 month, 2 months, 3 
months & unlimited.

WDYT?

Regards,
Glen
