Rolling back on lang tags for literals

Considering the difficulty and trouble that including lang tags
as part of literal nodes is causing, we did some brainstorming
about how we might live without them without huge modifications
to our architecture and came up with an approach whereby we partition
our schemas by language and maintain distinct graphs in the KB which
can be virtually merged as required for querying to achieve a form 
of language sentitive scoping of assertions.

It's a bit of work, but reasonable, and therefore lang tags
disappearing from literal nodes will not be as big a show stopper
as previously thought.

We therefore retract our dissent to the decision to remove lang
tags from literals, and would be able to live with their removal.

That would seem to make both the abstract syntax and the semantics
of literals easier for alot of folks.

P.S. We're still royally pissed off about the string-based semantics ;-)
