 * Fix all warnings about non-explicit constructors except for those
   in 3rdparty code.

If no 'qmlviewer' executable is found in the PATH, iterate through the
list of configured Qt versions and try to find a qmlviewer there. This
should help users configuring creator such to play with Qml.

Right now the first qmlviewer found in a Qt version is selected. A UI
to let the user select one explicitly was not possible any more (string
freeze).

This requires a dependency from QmlProjectManager to
Qt4ProjectManager.

 * Add function to check whether the new symbian build system is used
   to build a Qt version. This will be used to decide which parsers

  * Use id() for methods returning a string used to represent
    some type of object.
  * Use displayName() for strings that are meant to be user
    visible.
  * Quieten some warnings while touching the files anyway.
  * Move Factories to their products in the plugins where that
    was not done before.

Don't loose focus, don't loose the current index.
Implemented in a not really good way. The model emits a signal after
renaming, which the view respsonds to by setting focus/currentIndex
correctly.

Should fix a lot of corner cases, might introduce a few bugs.
Also rename functions/slots to be better named.

Generic Project Manager and CMake Project Manager are missing from this
patch.

Users can specify a S60 SDK root for Qt for Symbian versions
now.

That is we actually parse the mkspec and evaluate QMAKE_CXX (and a few
other variables) to figure out the correct mkspec. This makes using
custom mkspecs easier and is also cleaner. I also changed mkspec() and
mkspecPath() to behave a little diffrent, essentialy mkspec() will
return only the name (the actual dir name) of the mkspec. That is in
general not sufficient for passing on to qmake. mkspecPath() only
returns the correct path to mkspecs/default.
Hopefully I haven't broken WinCE/Maemo/MinGW.

Rationale: The concept of a "Qt Dir" is dead ever since Qt can be
installed. Specifying the qmake location otoh makes it possible to
unambigously detect all parts of a Qt installation.
