Set date/time in mail body not just subject

[jonasc]

Currently one can only set the date/time the mail should be sent in the subject. But for responding mails in gmail, if you change the subject the later sent mail does not show up in the same thread.

It might be possible to solve that by allowing a date/time to be passed in the message body. Suggestion: If the first line starts with an @ the rest of the line should be treated as a date/time specification

example:

@ 5.10.12 8:00
Hi Bob.

Thanks for the wine!
