custom ctrl-KEY mappings

[sgbeal]

An addition for cli.js, in keypress():

if (this.sticky.keys.ctrl) {
  if( this.sticky.keymap && this.sticky.keymap.ctrl )  {
    if( letter in this.sticky.keymap.ctrl ) {
        this.sticky.keymap.ctrl[letter]( this );
    }
  }
  else  {
    if (letter == 'w') {
        this.deleteWord();
    } else if (letter == 'h') {
        this.deleteCharacter(false);
    } else if (letter == 'l') {
        this.clear();
    } else if (letter == 'a') {
        this.setPos(0);
    } else if (letter == 'e') {
        this.setPos(this.buffer.length);
    } else if (letter == 'd') {
        this.runCommand('logout');
    }
  }
}

The keymap can then be configured like:

Terminal.sticky.keymap =
{
ctrl:{
w:function(term) { term.deleteWord(); },
h:function(term){ term.deleteCharacter(false);},
l:function(term){ term.clear(); },
a:function(term){ term.setPos(0); },
e:function(term){ term.setPos(term.buffer.length); },
d:function(term){ term.runCommand('logout'); },
}
};

with that in place, we can remove the "else" block above.

good thing i pasted that here, because i lost the code during the forking/merging process. it's been committed to my fork:
