Bluez 3.x and (kdebluetooth) pin helpers.

After being a bit disappointed that Bluez-utils 3.x simply doesn't accept old pin-helpers, like kbluepin from kdebluetooth, i thought about the best solution for this. Of course, we should develop a new pin helper, which can communicate with bluez over dbus.. and with kde4 supporting dbus it will be very easy.. but in the meantime, you can enjoy this patch. It modify the standard pin agent, so that, instead of giving it the pin as argument, you can give it the path of the pin-helper to execute. I'm using it in the new version of the live cd of kmobiletools. Hope you like it!
