Implement bean discovery in explicit and implicit archives

http://docs.jboss.org/cdi/spec/1.1/cdi-spec.html#bean_archive

1. Create CDI 1.1 project.
2. Create other CDI 1.1 projects and export them to jars or to class folders,
these projects may vary in beans.xml:

• no beans.xml
• empty beans.xml
• beans.xml with 1.0 schema
• beans.xml with 1.1 schema and all possible values
  of bean-discovery-mode attribute ("annotated"/"none"/"all")

and have classes with and without scope declaration.

3. Add these archives to classpath of project (1).
4. Create a bean with injections to types defined in the archives.
5. Check that injection is satisfied or not according to bean discovery rules given by specification.

Examples:

• Archive has no beans.xml: only annotated beans will be resolved;
• Archive has empty beans.xml, or beans.xml with 1.0 schema: all beans will be resolved;
• Archive has beans.xml with version 1.1: beans will be resolved according to the value of bean-discovery-attribute.
