By moving the completion settings into the TextEditor plugin, so that
both the CppTools and the QmlJSEditor plugins can access the settings.

The user-interface to edit the settings is still in the CppTools plugin,
since we're in string freeze at the moment. It should be moved to the
TextEditor plugin later.

For now the QML completion only supports the case-sensitivity and
partial completion options, since there is no automatic insertion of
brackets.

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.
