GlueGen JavaCallback: Add capability to have UserParam as (part of) key
Resolves use case where UserParam reflects e.g. a context (AL_SOFT_events)
and will be (part of) the key mapping.
Implementation required an additional userParamID -> userParam mapping for default Object/ID usage.
Added 2 test cases.
