Changements

reactor, app server: Add content-type to response
 (commit: fd3252f)

gs-reactor: Avoid traversing the whole context tree on flush/unmount
Listen directly for changes to the differential property in the cache,
since it is now accessible from the context.
 (commit: 822e5d0)

Return Observable<String> instead of ObservableValue<String> for
TextBinding
Some text bindings used <some snapshot>.toObservableList and the
subscriptions were not disposed. This way of doing things allows
disposing subscriptions when a DOM node is destroyed.
 (commit: b177874)

gs-reactor: Use Observables to define metabindings
– Use Observable<Snapshot<Generic>> to define a forEach and
 Observable<Optional<Context>> to define a select metabinding.
– Adapt the existing applications to this change.
– Allow sorting of Snapshots.
– Dispose subscriptions to the observables used in metabindings.

gs-reactor: Fix step count in @Stepper
 (commit: 4a155ef)

gs-reactor: MetaBinding: Rename some parameters
 (commit: 7f3211d)

Use hide() before returning Subjects as Observables
Avoids the possibility of a subscriber’s modifying the emissions.
 (commit: 16299b5)

gs-reactor: ApplicationServer: Avoid null pointer exception
Check that the root DOM node is not null before destroying the
associated context when the websocket is closed. The root DOM node can
be null if the page is reloaded before it was completely built.
 (commit: bfbf4d6)

gs-api: Snapshot: Add removals to result of getIndexedElements()
This allows getting all the changes in only one method. However, it
can’t be used in MetaBinding because, for each added child Context, an
Observable indicating when to create or delete an associated DOM node 
depending on the values of the ObservableValues returned by the
Switchers is created.
 (commit: 8ed4165)

gs-reactor: Add comment in Controller
 (commit: 9d7eb0e)

Refactor: getAdds/RemovesObservable() -> getAdds()/getRemovals()
 (commit: 62964fd)

gs-reactor: Add missing classes for HTML tags
 (commit: f24f3bc)

gs-reactor: Use Observable<Boolean> to define TagSwitcher
 (commit: d534c26)

Do not return ObservableValues in methods in DefaultCompositeInheritance
Return Observable<Optional<T>> instead of ObservableValue<T> for 
getObservableAttribute, getObservableHolder, etc.
To return an ObservableValue, it’s necessary to use the
toObservableList() method from Snapshot, which is deprecated since it
does not allow unsubscription from the Observables subscribed to in the
method.
Emit items of type Optional<T> rather than T because Observables can’t
emit nulls.
 (commit: 08a081e)

gs-reactor: Refactor
Remove ObservableValue/ObservableList from functional interface names
whose functions don’t return ObservableValues/ObservableLists.
 (commit: 4d2aa4b)
