Latest qt renamed qml executable back to qmlviewer, and also named
the executable again QML Viewer instead of Runtime/Launcher.

the method name got changed in 5732a440.

When adding a new file, refreshing semantic errors in the open editor should
have worked. It now also works for removing existing files.

So now the "Applciation Output" can distinguish between these four, and
handle them appropriately.

By introducing the OutputFormatter, RunControls can influence the formatting
depening on the application started. A nice (and intended) side-effect is that
the QML runtime specific formatting will not interfere anymore with anything
else.

Remove all hacks/conventions of considering the last generated
file as project file, etc. and instead add attributes flags to
Core::GeneratedFile, giving fine-grained control of what to do
with the file. Implement static utility functions in wizards
that handle it. Add boolean XML-attributes "openeditor"/"openproject"
to the file elements used by the CustomWizard XML-specification.
Manually set the attributes in all wizards.

The QML task manager behaviour is to show warnings/errors for _saved_ files
only.

It's not yet possible to attach to an external app running a qml
debugging server, because the server is only started on startup if an
env variable is set. Changing this requires action from Brisbane, but
even the current solution works for C++ apps with QML in them.

Previously we just scanned every directory containing a qml file for
other qml files.

This makes import ".." work.

Only watch directories, and not single files. Also, share one
FileSystemWatcher between projects & FileFilter items.

This fixes the issue that the process runs out of file handles e.g.
when loading a .qmlproject file containing all of qt examples & demos.

Basic implementation of FileSystemWatcher was copied from
ProjectExplorer::FileWatcher - however the FileWatcher is only
for files (and not directories), and also monitors the last
change date etc.

E.g. "QmlFiles {}" now also monitors subdirectories by default, while
"QmlFiles { paths : ["bla.qml"] } does not.
