creating a debug run configuration. Import the debugger
into Qt4ProjectManager.

and ApplicationRunConfiguration to LocalApplicationRunConfiguration,
preparing remote debugging. Change the interface canRun() to be const,
run() to create() (since it does not run anything), use references
to the QSharedPointer<Foo>. Introduce d-Pointer and remove
unneeded headers from ProjectExplorerPlugin and add missing includes
everywhere.

Since we can easily do that, just do it. No gurantee that we aren't
going to use rtti in the future.

Default to the baseName() of the .pro file.

One less need for qmakestep.

Transform the method in Qt4Project into a signal that is handled
by the run configurations themselves.

The runner uses the applicationlauncher internally, which is now
exported from the projectexplorer plugin for that reason.
