tomcat manager module and state

Hi Guys,

This is a module/state to manage tomcat webapps via the manager webapp.
I've being relying heavily on webapps versions for this.
http://tomcat.apache.org/tomcat-7.0-doc/config/context.html#Naming

Currently supporting only one version per context and support deploy of war files,
But this could be extended very easily to support context.xml & directory deployment.

I'll be happy to hear your thoughts about this module.
