Simplified Arquillian configuration
Cluster configuration
@ViewScoped CDI Extension

 - inserted Seam implementation of @ViewScoped context CDI extension
 - removed all seam dependencies
@FacesConverter converted to @Named @ApplicationScoped

 - seam contained extension to report converters without @NormalScope
 - extension was removed by previous commit, this fixes the scopes
 - fixed usage of converters
IDEA configuration uses Maven package goal

 - Manifest.MF is generated only by maven, it was missing in IDE's builds
Removed PrettyFaces

 - this dependency came with Seam
 - it breaks clustering, cause is unknown but the result is lost session
Commented out BeanBase debug information about session in cluster
