DestinationName in open() prototype

It implements DestinationName in pdfMake.createPdf(docDefinition).open(DestinationName);
its open the pdf document in a iframe or a frame, otherwise in a popup window _blank
For testing remember to put the iframe or a frame BEFORE the pdfMake.createPdf(docDefinition).open(DestinationName);
thanks for this Great Lib!

how about letting the user open up a new tab with specified name (instead of default _blank)? this would let him/her open previews in a specific tab

on the other hand, if no frame is detected - no alert will appear and instead a new tab will come up

what do you think?
