Unifying the api and exposing the options.

Missing files should be a warning.

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.

this properly.

We are checking for duplicate ids and duplicate property definitions now.

The "value might be 'undefined'" warning triggered whenever the static
expression evaluator failed to produce a value. At the moment, it does
so for almost all non-trivial expressions.

The warning is now disabled.

Link now caches imports. That means importing the same library (say, Qt)
from more than one file no longer creates an importing namespace for
each one. Instead, a single one is created for the instance of Link.

To make this work, the type environment in ScopeChain has been given its
own type: Interpreter::TypeEnvironment. That has the added benefit of
being able to carry meta-information about imports. You can use
TypeEnvironment::importInfo(qmlComponentName) to get information about
the import node that caused the import of the component.

* If possible, create LookupContexts through SemanticInfo; it caches the
  linked Context and will be faster.
* Contexts now own their Engine.
