[plt-scheme] Usability: delete whole line in DrScheme

I've been asked for this one for years and ... well, its finally time to do it.

Anyways, I've added something in to SVN to make control-a and the home
key respect the prompt in the interactions window.

It isn't quite right, tho, since the level I added it doesn't have
access to the proper selection extension information, but it should
work well for what you describe below.
