Allow hover to accept a single argument.

[micmath]

Would be useful when a hover argument function simply toggles a state, that is the fnOver and fnOut are identical.

for example var toggleState = function(e) {

$(this).toggleClass('over');

};

prefer to do this... $('#myId').hover(toggleState); versus the current... $('#myId').hover(toggleState, toggleState);

this is probably a wontfix. dup of #3498 (I tried to suggest this same thing there, and was shot down on the basis of confusing the dev when they only register one)
