Two new services: pari-commit and pari-bugs

[Bill Allombert <Bill.Allombert@math.u-bordeaux1.fr>]

Dear PARI developers,

I set up two new services on the pari server in the form of two 
read-only mailinglists that you can subscribe to:

pari-commit: this list receives notification of code commited to the PARI SVN
repository.

pari-bugs:   this list receives copy of bugs report and follow-up sent to the
PARI bug tracking system.

How to subscribe:
To subscribe to a mailinglist, simply send a message with the word "subscribe"
in the Subject: field to the -request address of that list.

As in:          To: listname-request@pari.math.u-bordeaux.fr
                Subject: subscribe

where listname is either pari-commit or pari-bugs

To unsubscribe from a mailinglist, simply send a message with the word 
"unsubscribe" in the Subject: field to the -request address of
that list.

As in:          To: listname-request@pari.math.u-bordeaux.fr
                Subject: unsubscribe

(The lists are managed with smartlist).

Cheers,
Bill.

PS:
Let's says this is an experiment to see whether the mailing-list set up on pari 
could accomodate more lists (hints hints).
