While reloading a text document, the bookmarks got lost since their
associated QTextBlocks were deleted.

This patch makes sure that before reloading, the bookmarks are removed
non-persistently in the same way as when closing a document, and that
they are restored after the document was reloaded.

Currently, no effort is made to update the location of the bookmarks
based on the way the file changed.

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.

Some Qt Designer actions stayed visible and/or active while editing
source files or when using the QML Designer even though they shouldn't.
Fixed that by applying some manual context handling in the DesignMode.

This patch replaces all uses of QSplitter with thin 1-pixel
splitters. I also fixed dock widget layouts in main windows
to do the same. Additionally I had to tweak the tabbars so
they look good in mini splitter layouts to avoid a double
left-border.

There no longer is a need for special currentEditorChanged()
handling in the editor that use a special mode.

QmlDesigner receives an additional setting specifying the
desired edit mode. QmlJSEditor detects whether QmlDesigner
is present by checking the registered mimetypes of the
Design mode and retrieves the settings via keys.
