Use native e.detail click count in event.addMultiMouseDownListener

[danyaPostfactum]

Fixes #978 in non-gecko browsers .
WebKit need this to support native d'n'd properly.

    if (e.detail > 1) {
        clicks++
        if (clicks > 4)
             clicks = 1
     } else {
           clicks = 1                
     }

seems to work relatively well for all browsers, but quad and triple click timeouts are wrong, i think they must be shorter than double click

[danyaPostfactum]

They are shorter in Firefox implementation. But all windows apps I tested have the same timeout for all clicks in a row. Opera ignores system setting and uses it's own timeout.

So, can it be merged? I'm updating my native dnd branch.

I'm updating my native dnd branch.

Cool! Looking forward to that.

I am not really sure about this, 4-click timing feels too off, but maybe i am unnecessarily picky about it.
Can you include this in dnd branch? Then it will be easier to decide what to do. use this or search for another workaround.

closing since this is included in #1431

There is the issue in IE. It does not take into account distance between click locations. I file the bug here.

Funny, now they do not take into account even the time between clicks #1751 :)
