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.

Also makes the code a lot smaller.

Closer again to qmake, ossi won't like it, but this is exactly what
qmake does, even it it looks a little bit strange. He can come up with
a better fix after he is back from vacation.

Previously, the image used as background forced it to be white, which
made the text impossible to read when the palette foreground color
happened to be white as well.

Since we can easily do that, just do it. No gurantee that we aren't
going to use rtti in the future.

Let's not irritate MSVC

Also adding category folders for the different file types
(source files, header files, resource files, form files, other files).

- Add methods to obtain executable from the run configuration
  (to be used by Debugger later on)
- Log the file names and sizes
- Pass on CreateFile() errors.
- Rename class Adapter to Launcher.

Default to the baseName() of the .pro file.

Consistent with the way the summary is written.

Task-Nr: 259513

This isn't a nice fix but the least evil version of a hack i could come
up. The source of the flickering is: We have a deeply nested structure
of widgets on the project pane. If we call hide() on such a deeply
nested widget, it will activate() it's parent layout synchronously.
That will then post an event (via updateGeometries() ) to its parent
layout that it needs relayouting. Which then will post to its parent
layout the same. And for each LayoutRequested, there's a painting in
between. The fix instead calls activate() up the chain until we are at
the viewport. This immediately relayouts everything. This adds a non
obvoius potentially for breakeage if the widgets are embedded in a
different widget hierarchy. But well, that's life.

- Give the controls a tooltip listing file details (date)
- Make building a QtConcurrent task
- Make log window scroll to bottom and pop up on error
- Make the build code pass on error messages about copying the
  source files to the log file
- Clean up the building code string-wise, use QLatin1String and
  translate messages, cache the icons. Use a QSharedPointer for
  the QtVersions in the settings page since they are passed to
  the BuildTask, which may outlive the dialog.
