* 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.

 * Make use of the ProjectConfiguration base class in the
   BuildConfigurations and update the factories accordingly.

They do what you expect them to do, that is build only a subtree.
The implementation is a little bit strange. We temporarly set the sub
node to be built on the BuildConfiguration, enqueue that
BuildConfiguration (which calls BuildStep::init()), and then reset that
temporary value.

A more general way would be to have the ability to extend
BuildConfiguration::buildProject() in a way that additional data can be
passed to the BuildSteps.

Instead note that it is invalid if trying to build and on the projects
mode pane.

  * 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.

The only part that is not done if not on Windows (or explicitly
specified) is the adding of the preference pane.

Task-Nr: QTCREATORBUG-277

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.

Move the code that compares the Qt version's debug|release property
with the build configuration's debug|release property
to the new build configuration class.

Rename arguments to allArguments(), qmakeArguments() to userArguments()

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

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.
