Ticket Notification Formatting

[Gökdeniz Karadağ]

Hi, thanks for this plugin.

Formatting for ticket notifications can be improved. First, the horizontal rule after "Changes" is not on its own line. I get e-mails like this.

....
Severity: Normal
---------------------------------------------------------------------
Changes (by xxxxx): 

 * Cc from 'yyyyy' to (deleted)
 * Priority from 'High' to 'Low'---------------------------------------------------------------------

I believe to fix this , {% end %} at ​ticket_email_plaintext.txt, line 25 should be on its own line. But I'm not sure about it. The horizontal rule may even be removed and replaced with a blank line, just like in original trac notifications.

Ticket property list can be like trac's own notifications ​format_props function may help. I am not sure if plugins can use core trac functions but at least it can be duplicated.

currently Announcer links only to the ticket's URL (.../ticket/230). Original notifications put a link to exact comment (like ​http://example.com/trac/ticket/230#comment:4 ). That would be useful to go to a specific comment in a ticket with lots of comments.

Would also like to see fields listed in two columns like in the default Trac emails.
