gst-launch tab-completion!

[Matt Pekar]

Thanks David!  It loads fine now and I've tested a few simple pipelines
with it.  The only unusual thing I've noticed so far is if I pipe a caps
with video/x-raw-<tab> it doesn't pick up any of those options.  Otherwise
seems very smooth!

I'll let you know what I run into as I use it over the coming days.
