support for jetty-distribution-9.2.2.v20140723 (requires modules), Init script for Centos, Logrotate script

Hi guys!

I made some changes in order to support :  

1. latest jetty version that needs modules directory jetty-distribution-9.2.2.v20140723
2. Use the default start.ini
2. Init script for Centos/Red Hat systems
3. logrotate recipe

Please let me know what do you think.. 
thank you,
Eugenio
