NVP + traits changes

Browse Source 
Added more NVP info to types that need it

Adding ability to detect a save function (member or non-member) that is incorrectly declared as non-const.  This is
needed since some nasty compilation errors crop up if you explicitly specify a serialization type and register that type
with an incorrectly constified save function.

So not done yet, but soon in: using a non const save function will trigger a static assertion.

Still need to investigate registering types with explicit disambiguation
