Mathias Kresin 80952f29b0 middle mouse button triggers event for all browser
This is a follow up to #1. The onclick event is triggered by different
mouse buttons across browsers:

Firefox
- all mouse buttons trigger document.onclick (https://bugzilla.mozilla.org/show_bug.cgi?id=430310)
- only left mouse button triggers document.body.onclick

Internet Explorer
- only left mouse button and without any modifier key triggers
  document.onclick

Chrome
- left & middle mouse button trigger document.onclick

Safari
- left mouse button triggers document.onclick
- middle click via mac os?

By switching to the onmouseup event this can be unified for all
mentioned browsers to:

- (CTRL+) left click triggers event
- middle click triggers event
- right click does nothing
