Doing it creates huge delays, because it resolves to a network path.
Also rename FolderNode::setFolderName to FolderNode::setDisplayName,
because that's the name of the property.

Task-number: QTCREATORBUG-695

Check for the case that a new file to be added to a .qmlproject
is also automatically covered e.g. by a wildcard filter. In this
case we don't have to do anything.

The old code still assumed the old, plain text format, and just added
the file path to the end of the file. This broke the new .qmlproject
file format.

Ideally QmlProject should be clever enough to check whether the file
will be automatically picked up in the monitored directories, and if
not added explicitly e.g. to QmlFiles { paths: ... }. Anyhow, this
quick fix just shows every time an error message instead of destroying
the .qmlproject file.

Putting every class in it's own files + avoid "using namespace"

This is in preparation of the addition of "targets" in the sense
of "platforms to develop for" into the codebase.

Old format is still available as a fallback.

For folder nodes.

Hopefully it was the same bug.

Fixes issues with handling additional dots in the filename in many
places.

Task: 246390

The name is used as the base for files like [project].creator,
[project].files, etc. and is displayed in the Projects mode and the
Projects tree.
