New DSP debugger: step one. (not ready yet, but try loading zelda WW and look at the dsp debugger..).

Had to shuffle around quite a lot of code to be able to extract the CodeView into a library nicely so it can be used from both the main dolphin and the LLE plugin...  also extracted the symboldb code.
