Cut down update times of Outline by a magnitude by only emitting
itemChanged signal if absolutely needed. This doesn't include the change
of the icon, because QIcon is missing a comparison operator ...

 * This unbreaks restoration of some steps.

The incremental update is not working as expected.

That is: a) Figure out a suitable default location for Add New on a
virtual folder.
b) If that default location is deployed, don't show a Add Existing Files
option, since that is confusing.

That is tell the user that those files need not be added to any project,
and show "<Implicitly Add>" for them on the last wizard page.
This fixes Add/New for the QML/OTHER_FILES folder structure, except for
the virtual folder itself.

Creating LookupContext seems to be expensive, so don't update anything
unless debug mode is already running.

Easier to use now by just clicking on one button, and takes less space.

A new debugger engine, QmlCppEngine, is introduced, which wraps gdb
and qml engines into one. Alternatively, if using Windows, Cdb is used
instead of Gdb.

Most of the debugger ui switcher is now rewritten, and it is tailored
for the QML and CPP layout case, the only one supported anyway.

Make sure DebuggerRunner::finished() is always connected to
handleFinished() (even for subclassed DebuggerRunners). Add
some more debugging information.

 * Enable support for this in all ProjectConfiguration items
   (Targets, projects, BCs, DCs, RCs, etc.). This is nicer
   than having custom code in individual configuraiton items.

DebuggerPlugin::startDebugger(), which connects the

to DebuggerRunner::start() to make it self-contained.
Add object names to engines for easier debugging.
