events mousehover, mouseactive

[lega911]

hover and active are both one-way bindings - they are events, so probably we can itegrate them to @events, we can add modifier "model" to declare that we use model instead of js expression.

@mousehover.model="model"
@mouseactive.model="model"

for "hover" we can use "mouseenter + mouseleave"

@mousehover.model="model"
==
@mouseenter="model=true" @mouseleave="model=false"
for "active": mousedown + mouseup + mouseleave

In this case maybe another directive would be great (especially für mobile applications):
al-isvisible

When the visibility state of an element gets changed, it should toggle a boolean model variable.
I think it will be hard to implement, because there are no events which can be watched.
