[Phoenix] Readline/Emacs Keybindings

[Andreas Wuest]

Hi

For those who do not follow commit messages that closely, I've 
implemented readline/Emacs key bindings for all platforms at the end of 
last week.

The bindings are as follows:

C-a: jump to beginning of line
C-b: move to previous character
C-B: move to previous character and select
C-d: delete
C-f: move to next character
C-F: move to next character and select
C-h: backspace
C-k: delete to end of line
C-n: jump to next line
C-N: jump to next line and select
C-p: jump to previous line
C-P: jump to previous line and select
C-u: delete complete line
C-w: delete previous word
C-W: delete next word
C-_: undo

Where "C" means "Ctrl".

If you have ideas for further key bindings, please tell me. Depending on 
their complexity, I can then go and implement them.
