bsdinstaller / partedit emacs key patch

Hi,
I noticed that the entry widgets in the bsdinstaller label editor don't understand various "emacs keys" (eg C-a, C-d, C-e). 

Here's a patch which adds the basics.. Unfortunately dialog doesn't have a "key" for delete all, delete left or delete right so I couldn't add C-u, C-w or C-k.

Note that you can't just call dlg_parse_bindkey("* ^a BEGIN") because dialog modifies the string which crashes (seg fault).
