The distinction between QmlJS and QmlJS::Interpreter has always been
weak and the extra namespace just added an unnecessary complication.

Previously Context was not entirely thread safe and had to be
copied locally. Now it is thread safe and its lifetime
managed by QSharedPointer.

The non-safe parts were moved into ScopeChain in a previous commit.

Context is created by Link and has information about imports
for all Documents in a Snapshot.

ScopeChain represents how lookup is done at a specific place in
a Document.

The problem was that several lookup calls suddenly failed because
the actual QML types were no longer in the default scope chain. However,
the QML documentation says the type names are in the scope.

Also, 'MyComponent.' in a JS-expression context only showed the attached
properties of MyComponent and missed the enums.

With this change completion now may offers too many options, but that's
better than missing some.
