React to changes in observables

[anton7r]

Reactivity finally yes!

we do not have reactivity yet implemented in the framework.
i would want to finish this feature within this year and ship version 4.1.0 with it!

ive experimented with few things on how the syntax could look like

These are few examples:

<div>Watch{{ observable }}</div>

<div>w{{ observable }}</div>

<div>Watch@{{ observable }}</div>

<div> {{ &observable }}</div>

and also the the watchable has to be a a7js observable.
