The functionality was duplicated between the Qt4 and CMake build
configurations and their configuration widgets. This change moves it
down to BuildConfiguration, in addition also making it available for the
Generic Project.

Also provides an upgrade path for the configuration.

Environment variables will now be expanded in the Generic Project file
and include path lists. They have to be written like $$(VARIABLE), like
in qmake .pro files.

Task-number: QTCREATORBUG-366

Unused stuff.

Don't mess up the original structure of the generic project file list by
reconverting all the paths to be relative from the project directory.
This allows whitespace or absolute paths to be preserved even when
adding/removing files through Qt Creator.

 * Ease cross device development by introducing 'targets' which
   group build- and runsettings that are valid for this one target

 Most of the kudos for the code review go to dt. Con, thorbjorn,
 ckandler and others did also review parts of this patch.

  * Use id() for methods returning a string used to represent
    some type of object.
  * Use displayName() for strings that are meant to be user

    * Remove entering/leaving directory related code from all other parsers

Note: I didn't fix all the connects and there are a few missing things.
This compiles, more work is coming.

The pointers can be used to distinguish BuildConfigurations

The project() should in most cases not matter, instead the
BuildConfiguration should. This shows all the information that needs to
move into the BuildConfiguration classes.

More API work.

Each project has it's own BuildConfiguarion * classes, they'll get a
decent type safe interface and the setValue/value stuff will be removed.

Enables users to change which buildsteps get run per buildconfiguration.
Some further tweaks are probably necessary. This is a rather big
change, though it should work. :)

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.

Also move Designer::Internal::FormWindowEditor ->
Designer::FormWindowEditor.

It's easier this way for the unique naming.

Instead use the BuildConfiguration class methods directly.

Builds, but I'm pretty sure it doesn't *work* :)

.. and purge unneeded includes.

Made virtual newBuildConfiguration return a bool

Some fixes were needed after the tool chain type was changed from
QString to an enum.

This has still a few missing things, but this enough to start getting
some feedback. Missing are non qt projects, a solution for the
runconfiguration, a missing black line between the treeview on top and
the project settings at the bottom. Some flickering with removing/adding
widgets to the QScrollArea and not showing the expanded widget if the
Details button is right at the bottom.

Add missing Q_OBJECTS where tr() was used.

E.g. cmake pops up a wizard then, the running of cmake can fail though.
Now you don't end i[ with a empty project then. The error reporting in
that case is not yet optimal.
