#2 Add a batch function to email requests

[Tim Esau]

For a subject line called "list" or perhaps "parse" allow
multiple commands in the body of an email so that the
email user could batch up a set of Phoo querries or
commands.

Subject: parse
body:
stats
seen rjf
recall 1d
msg rjf Bleach!

Potentially abusable. Maybe a good idea to assign a ceiling of
5 commands or so.
