[gaim-migrate @ 13226]

I started this a long time ago, and decided to finish it.  This adds a AM_PATH_GAIM macro to aclocal.  Very useful for plugin developers.  It works alright so far, but isn't tolerant of an non major.minor.micro version being passed to it.  I'm still considering moving the meat of this to a compile test, but this will do it for now.
