[ENH] Immutable objects

[Brian Rice]

#freeze and #isFrozen are now available in src/lib/immutable.slate  
and mostly work but need improvement, maybe a whole-sale refactoring  
later. #thaw, well, would just alias #mutably so I have not thought  
it relevant to add. When someone tries to actually use this protocol,  
please report requests or something.
