Hi,

Here is the patch vs revision 6132 for adding exposed pad to qfp_wyzard

I added the exposed pad option and changed name from QFP to QFP/QFN.
I used the function PadLineArray because I couldn't find the apis doc...
anyway it should be fine.
I assigned 0 to exposed pad pin number...
please let me know if it is fine or if I should change it to maxpin 
number +1.

Thank you,
Maurice
