Cdi 1.1

Merged master into cdi-1.1. Added Weld-2.0 integration. Tested with port of Igor's cdi examples running on Tomcat 7.
Both cdi-1.1 and weld-api-2.0.Final are set to provided scope. This allows the end user to set the proper container jars in the app. If not Tomcat will get a jar validation error and user will have to set up exclusions etc.etc. 
Example App for this can be found at https://github.com/jsarman/WicketCdiExample
