added DLL exports (it builds now!)

rewrote error checking mechanism
fixed some opcode cases not being right
fixed various opcode and codegen bugs
fixed stack alignment problems
made proc aligned to a dword
fixed up helpers naming scheme
started marking opcodes as either working or not working
probably more -- too much to list
