Tomcat Variable (#13)

* Tomcat Variable

I don't know a good way to know which tomcat version is already running, and of course someone could theoretically run more than one...so the upgrade script is just a variable but the install script will check apt-cache and try to install tomcat8, then tomcat7, then tomcat6...

* Optional commented line

Added a commented out line in case someone wants to force an older/specific tomcat install
