edit person page
Added option for embedded Jetty to scan folder of created *.class files
every two seconds. Now you're able to start Jetty via Maven:
	mvn jetty:run
and every time you change Java code, the newly created *.class files were
read by Jetty without restart or any other manual step.
Added git ignorance file for temporary generated files of Eclipse and
Maven.
