the low level method htmlelement.classList.add does not accept multiple
classes in one string, which is why, in owl, the expression
`<div t-att-class="{'a b c': value}" />`
did not work as one might expect. It is however very convenient in real
life templates, so this commit improve owl by adding support for this
feature.

In some cases, a rendering initiated in some component is then remapped
into a larger rendering initiated by some parent.
If we have some components which implement shouldUpdate to return false,
then the following scenario can happen:
- some parent component is mounted (which triggers a rendering with
force: true => bypass the shouldUpdate)
- some sub component is updated and rerendered, AFTER the previous
rendering goes through it
- the sub component notices that there is an ongoing rendering, and
remaps itself in the parent rendering
Before this commit, the new fiber in the subcomponent does not have
force flag set to true, so the new rendering for the subcomponent does
not go through its own children (if they have shouldUpdate=false)
Another more complex kind of scenaria can happen when a remapped
rendering happen with sub components with dynamic shouldUpdate. The
problem is the same at the end: the new rendering should ignore the
shouldUpdate, to make sure we have the last correct information.
With this commit, we make sure that the flag of the new fiber is set to
true.

This commit performs two tasks:
1. it exports the internal browser object (in owl.browser), for ease of
testing
2. it makes sure that Owl does not crash inside iframes in incognito
mode, because window.localStorage raises an exception in that case

The documentation was a bit missleading around which and when css
classes were added to the DOM.
Also added a scss mixin usage exemple.

Fun: the transition is handled at two different places, once for dom
nodes, once for components. Obviously, I only applied the change to the
first case and forgot about the second.
It is useful to be able to disable the t-transition directive for
testing purposes. This commit introduces a global config flag to do
just that.

Owl is meant to stay low level-ish, and making it work magically with
sets/maps/... seems to be a little too much in term of code/magic. Also,
using iterables in t-foreach is actually quite simple, making this
improvement not as important.

This could be done by each application, but it does cost only a few
lines of code, and it helps standardizing the Owl ecosystem.
For example, some library (such as o_spreadsheet) needs to mock side
effects, and Odoo also needs to do that, so this prevents duplicated effort.

This new t-set-slot directive is meant to replace t-set when we need to
define the content of a sub slot. All new code should use that
directive.
The old t-set directive is still supported for now, but this should be
removed when we publish Owl 2.0.
In this commit, we uses the "!" as suffix to designate an event that
should be captured. This is inspired by the Vue source code.
This solves the issue of communicating additional information to the
underlying virtual dom. However, this will most likely disappear when
we rewrite the vdom as a virtual block system.
