the default keybindings

["Matthias Clasen" <matthias clasen gmail com>]

Here is a little curiosity I wasted a few hours on last night.

I added some documentation to text view signals, and thought
it would be nice to show the default key bindings in the signal docs.
After doing it manually for some signals, it occurred to me that
it might be possible to introspect this information, and I wrote
a little app that dumps out an rc file containing all the default keybindings.

Maybe this is useful for something, so I'll send it here.
