I noticed that mouse wheel events might trigger mouse avoidance. That
seems inappropriate. The attached patch should fix that.

Please notice that I am a bit unsure about what the event names could
be. There are probably more event names than those I have entered. In
keyboard.c there is the following code:

static char *lispy_wheel_names[] =
{
   "wheel-up", "wheel-down", "wheel-left", "wheel-right"
};

I have changed the code to make wheel events appear as click events 
(double and triple wheel events were already handled correctly).

I am still confused about all the steps an event goes through to become 
a Lisp event, as the click modifier was being set on the wheel events, 
but wasn't returned by event-modifiers, which seems to ignore the 
modifiers and just use the base name of the event to regenerate them. 
Are the modifiers we set in C code that untrustworthy?
