Add REPL hot-keys

[IBIT-ZEE]

REPL editor HOME and END keys not working (version 0.1.1.20912)
HOME should go to begin of editing line
END should go to end of editing line

as we are with 'hands' in this stuff:
ESC should clear the edition line
F2 for a list of all commands (history), ENTER put select in edit line
F3 open a dialog box to FIND a string (regex) in all the text
CTRL+HOME/CTRL+END should go to begin/end of text (all text in c# interactive window)
PGUP/PGDN should up/down 1 page

Great product... thanks...
