Extension request: extend block.js duplicate_ by a return statement

Dear all,

I implemented a functionality where it is necessary to duplicate a block and 
connect it to another. Unfortunately the Blockly.Block.prototype.duplicate_ 
function of block.js in the core folder doesn't return the duplicated block.

It would be nice if you could add a 'return newblock' at the end of the 
duplicate_ function. 

For the moment I added the above mentioned line by myself, but I believe that 
other users may would like to use the duplicate functionality in combination 
with the connect functionality as well. 

Best regards
Marc Wollenweber
