Initial import of servlet-security-genericheader-auth from Gary Lamperillo (Thanks Gary!)
Added readme and unit tests for genericheader-auth quickstart (from Gary Lamperillo)
Minor fixes to spelling and the license header (one was different from the others).
Fixed formatting issues
Updated readme to further describe Tomcat valves
Updated based upon latest feedback from Gary:
 - Switched to pass in only the user header.
 - Added instructions for using the RemoteHostTrustLoginModule to trust a system that does not provide a password header (eg, SiteMiner). This seems to be the common usecase for this type of module.
Fixed formatting and switched to cli for instructions
Completed scripts
Updated to version.jboss.as to 7.2.0.Final
