Revise the “there’s a new applicant” emails

[brittag]

What type of user is this for? (applicant/member/voting member/admin)

Members and voting members

Description

Shouldn’t email for every single applicant. Instead:

• Weekly digest for all members with a list of new applications - just the name and the link, encouraging them to comment (if possible, send to DU mailing list address so it goes into people’s usual mail filters). Goal: get members to comment on applications and sponsor applications, to help the voting members vote.
• Weekly digest for voting members (sent directly to them) - list of applications that need votes and are older than one week, ranked by closest-to-two-month-mark. Goal: get voting members to vote!
