Convert ValueObject to explicitly maintain the Execution Context in which they were created, and then use that when they update themselves.  That means all the ValueObject evaluate me type functions that used to require a Frame object now do not.  I didn't remove the SBValue API's that take this now useless frame, but I added ones that don't require the frame, and marked the SBFrame taking ones as deprecated.
