Non-osgi sample of jaggr, jaggr-web

Ignoring filter will prevent multiple servlets (using different aliases) from running in the same JVM, because the name property of the dictionary is used to distinguish between servlet instances.  There are open source ldap filter parsers available, but I think that we should at least provide support for the (name=<name>) filter string which is all that is used by the aggregator.  Anything more complicated and you could throw an UnsupportedOperationException.
