Task-Nr: QTCREATORBUG-1044

That is e.g. buildSteps() and cleanSteps() --> steps(type)

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.

   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.

Fix for that will come later

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.

 * Fix reordering of build steps in the clean list of steps.
 * Make the code more robust and avoid removing and inserting
   the item.
 * Update code for the build steps list too for reasons of symetry.

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. :)

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