Add a "Date:" header to the mail

[grg]

Hello,

I've installed trac-wiki-notify and one user reported that his mail client shows the date as follows:

Date: 12/31/69

This is because trac-wiki-notify does not add any Date: header, and some mail clients show a weird default date instead.

I've modified trac-wiki-notify to add the Date: header and would like to contribute this feature for further inclusion into the official version. Here is the patch:
