Defer application registration via an idle callback

A python application, for instance, may initialize gtk but not enter the
main loop. It would, thus, register with the AT-SPI registry but not be
responsive to queries. Putting registration into an idle callback ensures
that, if a program never enters the main loop, then it won't register.
