Write a function to select all unsent drafts

[mattkiefer]

work this into msg.compose.distribute so you can follow a two-step process:

1. prep drafts
2. send prepped drafts

[mattkiefer]

The tricky part is deriving the name of the agency the unsent draft belongs to ... that's required for msg.compose.sender() to assign the agency label on the outgoing message

[mattkiefer]

for unsent drafts:

1. delete all drafts
2. write a new function that gets all agencies without sent messages
3. pass those agencies to prep_drafts via contacts_by_agency

[mattkiefer]

report.report.get_threads() can check for unsent FOIAs

[mattkiefer]

all drafts are unsent so just make sure there is a way to select all drafts and distribute them
