[FIX/IMP]: t-foreach can interpret any iterable.

t-foreach accepted only arrays and object.
Now, iterables and objects are accepted.

-## `enableTransitions`
-
-Transitions are usually nice, but they can cause issues in some specific cases,
-such as automated tests. It is uncomfortable having to wait for a transition
-to end before moving to the next step.
-
-To solve this issue, Owl can be configured to ignore the `t-transition` directive.
-To do that, one only needs to set the `enableTransitions` flag to false:
-
-```js
-owl.config.enableTransitions = false;
-```

-Note that it suffers from the same drawback as the "dev" mode: all compiled
-templates, if any, will keep their current behaviours.
