Send CPU name to master on announce

Hmm, what do you expect `cpu_name()` to return?  Based on the doc string you have here I don't think `platform.processor()` is what you want because it's pretty inconsistent.  On my Intel based Mac it's i386 even though it's a 64-bit processor (because it's a 32-bit interpreter).  One one of my Linux systems it's returning x86_64 and another it's returning a blank entry.  Windows oddly enough is the only system right now where I see it returning the processor information itself (make, model and clock to be exact).  If you're looking for this kind of information we can repurpose or slim down #173 to add pycpuid in which would add the information you're probably looking for into this module.

Pretty sure the above is what you're looking for but if you are in fact looking for the architecture we can use `system.machine_architecture()` to retrieve that information which will work independent of the interpreter's architecture.
