This code used two hacks: it created a class with
metaObject()->className() == "QTipLabel" to fool the code in Qt into
applying the style properly to this class.

But it did that by creating a class called QTipLabel. This works as
long as the class in Qt is hidden by symbol visibility. When symbol
visibility is disabled (for whatever reason), then Creator simply
crashes due to size mismatches and memory corruptions (virtual tables,
etc.)

This patch makes the class be called TextEditor::Internal::QTipLabel,
but fools moc into thinking it isn't.

A proper solution would be to simply override the meta object.

It did more harm than good. Now, the auto detection is only done on
run control change - this is something that Creator could also remember.

Initialize e.g. m_itemToNode before the view calls back to the model.

Don't use QMultiHash::values(key), it rebuilds the values list from
scratch for each lookup.

Did not work e.g. for projects where non-project files are loaded.

Task-Nr: QTCREATORBUG-2069

Apparently, the sender can still be null even though it's deleted
via deleteLater().

This is needed for sourve packages, but interferes with binary ones.

The code is technically incorrect and easy to fool.
See the comment in the patch.

Instead let the project explorer plugin handle that.

 * Make the name of the configuration about to be removed more visible.

 * Update the Qt name when entering the path to qmake via the text edit.
   Behaviour matches what used to happen when selecting qmake via
   the file browser now.

Task-number: QTCREATORBUG-2145

Do not save Qt versions without a qmake set. Makes no sense to keep
those.
