Fix #337 - don't promt for sudo passwd for non-existing directories
Add some extra keybindings

`prelude-smart-open-line` is now bound to `M-o` as well
`prelude-start-open-line-above` is not bound to `M-O` as well
Remove M-O keybinding

It interfered with the Terminal's handling of arrow keys.

This fixes #343.
Map Option to Super and Fn to Hyper

More keybinding options is never a bad thing.
Add prefix arg to prelude-smart-open-line

With a prefix arg the command will invoke prelude-smart-open-line-above
