Cryptonote generator documentation added

Documentation for the Cryptonote generator was added. With the generator you can generate a separate source of any Forknote coins. This ability is valuable if you need an actual source or you want to extend the functionality of a coin.

The way to extend the functionality of a Forknote coin is through extensions. This ensures that the development of your coin constantly matches that of Bytecoin.

What the actual positives of using the generator instead of merging?

• In most of the cases it will save you the actual merging process
• It will save you the merge conflicts

The downside is writing extensions is slower than writing just a C code. But since the extensions are pure json, the process CAN be reduced to just writing a C code.
