PHP-FPM Ondemand PM

Hello,

I think that ajenti-v-php-fpm option "pm = dynamic" should be "pm = ondemand" by default. "dynamic" is pretty ineffective. "ondemand" is certainly better for most sites. It saves memory and system load. Maybe it would be good, if we could select the processmanager in GUI?

Right now I'm doing it by executing "sudo sed -i "s/dynamic/ondemand/g" /var/lib/ajenti/plugins/vh-php-fpm/phpfpm.py", but I have to run this command every time I update ajenti.
