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.

The problem was that for

Foo::Foo
(|)

when the user triggers completion at |, startOfLine() returns a token
that's not on the current line and not yet tokenized by that instance
of the BackwardScanner.

As a fix I explicitly ask the instance to tokenize up to the given
index.
