When a stream operator is applied to an unsupported type.

Added a "stream" binding expression operator.
Which is now required when wanting to get the value produced by a
Task/IObservable rather than the Task/IObservable itself. Fixes #711 .

Swapped names in ExpressionNode.
Swapped names of StartListening and StartListeningCore - method names
ending with Core should be the subclass implementation.

Try to improve logged binding errors.
- Don't log an error when the target for the root ExpressionNode is
null. This is usually because the `DataContext` hasn't been set up yet
and it spewed a load of useless error messages.
- Add a Description field to `ExpressionObserver` that can be used in
the case of e.g. #control bindings to record the whole expression (with
the "#control" part) rather than just the part tracked by the
`ExpressionObserver`.

Fix failing tests, add other tests.
Also use logical parent's DataContext as base for DataContext bindings
instead of visual parent's. Was previously in error.

Add concept of "value plugins".
These are used to extensibly handle special values like `Task` and
`IObservable<>`. Previously this was baked into the expression observer
architecture with a TODO comment saying that it needs to be extensible.

Started refactor of ExpressionObserver.
Tying to be more "rx", but also will allow us to move forward on BindingNotification changes.

Added BindingNotification.
This will replace BindingError and IValidationStatus for bindings that want to notify binding/validation errors. Still WIP.

Reimplemented property validation.
As far as it was in `property-validation-grokys` branch. Things were
messed up on master so had to merge this manually so may be problems.

Changed validation on controls to allow notifications from multiple types of validation and correctly report if it is valid. Changed initalization of validation plugins to nest within each other so there can be multiple active at once.

Finished wiring up validation support. Now exceptions and INotifyDataErrorInfo implementers will set controls into their ":invalid" pseudo-class state.

Renamed XamlBinding -> Binding
Had to also rename enclosing namespace from Binding to Data as classes
with same name as a namespace cause problems.

Wrote binding expression parser by hand.
Sprache couldn't cope with it as it requires a left-recursive grammar.

Use Sprache for parsing expressions.
Use sprache instead of Roslyn for parsing expressions. One test still failing.
