Speed up SeamELResolver by avoiding a full scan of all imported namespaces
--------------------------------------------------------------------------

                 Key: JBSEAM-4268
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4268
             Project: Seam
          Issue Type: Feature Request
    Affects Versions: 2.2.0.CR1
            Reporter: Riccardo Serafin

See post in the seam forum (http://www.seamframework.org/Community/212PerformanceRegressionInMessages) and JBSEAM-4244. 

Basically, I'd suggest two things in order to speed up the resolveBase method of SeamELResolver:

1) Avoid going through all imported namespaces when looking up a property by caching known component and factory names in imported namespaces at init time. 

2) Allow resolution of components used very often, like messages, before looking in all the stateful scopes, for sure at least before going through all imported name spaces.

Moreover, it would be nice to have some way to extend/bypass/configure the SeamELResolver to allow application dependent optimization.
