jQuery.on() and .off() have several unhandled overloads

[wmadden]

Their signatures are:

.on( events [, selector ] [, data ], handler(eventObject) ) .off( events [, selector ] [, handler(eventObject) ] )

but touche.js only handles the trivial case where events is a single event name.

Problem cases:

• events is a space-separated list of event names, possibly namespaced
• events is an object, which causes our subsequent slice() call to explode

On case 2:

Uncaught TypeError: undefined is not a function

Line 66 fails.

if (event.slice(0, 5) == 'click')
