[Neuclear-develop] neuclear-commons/src/java/org/neuclear/commons/servlets EnsureRequestHostFilter.java,NONE,1.1

[<pe...@us...>]

Update of /cvsroot/neuclear/neuclear-commons/src/java/org/neuclear/commons/servlets
In directory sc8-pr-cvs1:/tmp/cvs-serv5302/src/java/org/neuclear/commons/servlets

Added Files:
	EnsureRequestHostFilter.java 
Log Message:
Added EnsureHostRequestFilter to commons, to only allow requests from a particular IP
Added a method to optionally show the passphrase box in the SigningServlet. As the default SigningServlet
is intended to be used with a gui passphrase agent, we dont want to display it. 
The DemoSigningServlet does display the dialogue.
Added the new neuclear-signer package, which is a standalone web signer using Jetty. The project runs
when built with "maven javaapp". More testing needs to be done as well as a startup wizard.
