Add 10-key support.

[cthurston]

Add to special keys _MAP
* : 106

Map the 10-key:
_tenKey = {
'96': 48,
'97': 49,
'98': 50,
'99': 51,
'100': 52,
'101': 53,
'102': 54,
'103': 55,
'104': 56,
'105': 57,
'107': 187,
'109': 189,
'111': 191,
'110': 190
},

Then in dispatch:
if (_tenKey[key]) key = _tenKey[key];
