Add scripts/sendemail.php to send email to a user's address. Updated setup_status_network.sh to create a user with the site's nick, accept site tags, and send a mail to the user (if a template is set)

Email and tag params added to the end:
setup_status_net.sh mysite 'My Site' 'owner@example.com' '1user'

(If multiple tags are needed, separate them with a pipe "|". Be sure to quote properly!)

New parameters for setup.cfg need to be set:
export PHPBASE=/var/www/statusnet
export WILDCARD=example.net
export MAILTEMPLATE=/etc/statusnet/newsite-mail.txt
export MAILSUBJECT="Your new StatusNet site"

$PHPBASE is the base dir for a callable StatusNet install, used to run command-line scripts for user setup.
$WILDCARD is the wildcard domain, needed to build a full server name to pass into command-line scripts.
$MAILTEMPLATE points to a file containing an e-mail message template. '$nickname', '$sitename', and '$userpass' can be used in the template for substitution.
$MAILSUBJECT is the subject line for said email.

To skip sending an email on creation, leave $MAILTEMPLATE blank or point to a non-existing file.
