Make the event triggering the open menu action configurable.

[ZancaM]

For example change the opening of the context menu on single left (regular) click.

For now I tweaked the library myself for my purpose:
https://github.com/jonataswalker/ol3-contextmenu/blob/master/src/js/internal.js#L158
I changed contextmenu to click to enable the menu on single click.
Ideally this could be coming as a property when we create the object
new ContextMenu({
'event':'click',
...
})

@ZancaM I'm glad you reached a solution but I'm not sure about this. It looks like, for me, a bit intrusive.

Maybe you have some more arguments? Or others?

With #73 you can set the event type.
