Create generatetoaddress rpc

Browse Source 
Creates the generatetoaddress rpc which is virtually identical to the generate rpc except that it takes an argument for the address to mine to. It does not rely on wallet functionality.

The mining code shared by generate and generatetoaddress has been moved to another method to reduce duplication.
