 Hello,

 Using libpurple, it looks like that the only way that I can accept/cancel
 a file transfer is by registering for request_action and check for "wants
 to send you" in the callback.

 Also, there is no way to control the file-choosing on where the file is
 saved to. Both request-action and request-file are invoked within ft.c
 instead of a callback in the same style as
 PurpleAccountUiOps.request_authorize.

 Is it possible to add to PurpleXferUiOps (or update new_xfer) a function
 the way request_authorize does to accept/reject the transfer of a file?

 Likewise, it it possible to add a cb to PurpleXferUiOps to choose a file?

 Thanks.
