Fixed bugs dealing with double signals and linear scaling; added checks for scenarios where min==max; fixed passing of min and max arguments in test program.
Fix variable name bug.
Expression parser/evaluator: allow multiple sub-expressions for e.g. setting different vector elements/ranges.
Expression parser: eliminate TOK_QUESTION since it was really handled by TOK_OP, use bitflags more efficiently in token type enum.
Re-enabled instance updates, but switched to explicit tagging of instance property in message using @instance label as discussed long ago on the mailing list. Instance release messages now require OSC NIL types for each vector element.
Fixed some more instance-sending syntax.
Cleaning up signal handlers & obsolete typestrings; Fixed soem more instance message formatting.
Added some vector signals to testquery and testreverse.
