HasEventListener will always return false in IE 7

[zackpudil]

HasEventListener will always return true do to a IE 7 bug in the get_valid_types_first_letter method. The bug is due to IE 7's short coming of not being able to index strings like arrays. So this line:

var first_try = (/Object|(Ele|Docu)ment|Window/.exec(Object.prototype.toString.call(object)) || [""])[0][0],

needs to be this line:

var first_try = (/Object|(Ele|Docu)ment|Window/.exec(Object.prototype.toString.call(object)) || [""])[0].charAt(0),

If you wanna support IE 7.
