in payment capture function support for currency param added

[rvnew]

@rzpamidi new changes added.

[rzpamidi]

@rvnew , The last argument is a callback in all methods , please don't change that , instead try to do

write the function in such a way that if the third argument is a function , consider it as callback , else check if its a string and try to use it as currency , which would server your case and also ensures Backward compatibility.

@rzpamidi please check now.
