Donation of servlet control code (for Eclipse plugin)

[Ross Gardler]

The Burrokeet project (http://www.burrokeet.org) voted to donate their 
Servlet controller code to the Apache Forrest project. This code 
improves the way that the Forrest Eclipse Plugin starts and stops the 
Jetty server. The Forrest code was already dependant on the Burrokeet 
code, but Burrokeet only uses it in conjunction with Forrest. Therefore, 
in order to remove the dependency of Forrest on Burrokeet the code has 
been donated here.

I have relicensed the code (I was the previous Copyright holder) and 
committed it to 
tools/eclipse/plugins/org.apache.forrest.eclipse.servletEngine

This resolves issue FOR-503
