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.

Introduce some more private classes for the coreplugin,
use header include convention
<QtModule/QClass>, de-qobjectify VariableManager.

To make it work with the HistoryCompleter.

Rename 'QML standalone application' to 'QML application'
and the 'old-style' QML applications to
'QML Viewer based applications'.

For the QML renaming:

- Changed generator to generate:
- Changed AST::lastToken to return 1 if there is none
- Changed Bind.cpp to set the scope of the block following a control
  statement to extend upto (and not including) the first token after
  the block. So basically, including any whitespace after the control
  statement.

Also some less significant improvements.

There's a UI in qml/customexec/cmake/qmake run configs for choosing the
debugger languages (C++ and QML). The default for all except .qmlproject
is only C++, so default debugging behavior is the same. However, if the
user wants to do simultaneous debugging with two languages, or only
debug QML, they can select the languages from Run Settings and it will
be remembered.

Don't use QMultiHash::values(key), it rebuilds the values list from
