Removed the Big Scratch Buffer. Saves 4 kilobytes of heap per bytecode parse. Bytecode parsing now needs a little more stack space, but not 4 kilobytes, and it reduces silly logic tapdancing we had to do to avoid stepping on in-use scratch buffers. This took all day, touches every line of code, probably introduces bugs and doesn't introduce any new features, but I finally killed that crappy code! :)
