Made the cmake plugin even more usable by implementing:
Pop up a wizard if there is a .user file but no .cbp file. (Fixes empty
project reported on irc.)
Pop up a wizard if the .cbp file is older then the CMakeLists.txt file,
thus reparsing the file. (Note: There is a bug that we need to actually
also check the last modified of all included files.)
Reparse the cbp file to add new RunConfigurations / delete no longer
existing RunConfigurations and update those that have changed.-
Show a nicer title in the Projects/RunConfiguration pane

Task:     246282
Details:  call setFolderName()

Details:  Optimize addFileNodes and addFolderNodes. Probably has no
effect for qt4projectmanager.

Details:  That fixes a few bugs, while still having a few missing
things. Don't allow the user to set a shadow build directory, if there
is already a in source build. Detect if a cbp file is already existing
and recent enough, don't rerun cmake then. Ensure that the user runs
cmake with the cbp generator on opening the project. Show the output of
the cmake generator while running. Remove the unecessary cmake step.

Task:     CMake support
Details:  No syntax highlighting

Details:  This enables us to parse the build errors correctly.
          The makesteps of the qt4project and cmakeproject have some
          code dupliaction, which could be refactored. And the code
          to find out the correct build parser could probably also
          be done better, but we are now parsing the build output for
          cmake.

Details:  We now get the system includes and system defines.

Details:  Add a dialog asking for command line options and build
directory. This dialog pops up if you don't have a .user file. Note,
though that it also pops up if there is already a in source build.
(The build directory lineedit should be read only then.)
The cmake button in that dialog and the output pane need more polish to
make them better. With those changes you can now build and run marble
from Qt Creator. (For marble you need to pass a few options to cmake.)

Also add a configuration page to the Tools/Options dialog, where you can
specify the cmake executable path.

And add a class which runs cmake in the background to find out which
version and wheter that cmake version has Qt Creator generator. (Which I
did begin to write.)

Dependencies between projects can now be edited in the Projects mode.
You can simply check for each project the projects that it depends on,
and they will be built first. A message box pops up when you try to
create a circular dependency.

Could use some testing.

Details:  I haven't checked, but according to the cmake sources I need to change this.

- avoid polution of the source.
- required for KDE apps.

Details:  One step at a time.

Details:  Not yet usable, but at least you get a list of build targets now.

Task:     -
RevBy:    -
AutoTest: -
Details:  For now create only one build configuration "AllTargets",
build only the "all" target. Create runconfigurations for all targets
with option type=4

Task:     -
RevBy:    -
AutoTest: -
Details:  Note: I need to refactor the code significantly, i'm more or
less convinced that one build configuration per target is wrong.
We probably want one build configuration per build directory and instead
build all targets that we are interested then in the makestep.
This means we won't have any cmake support for the beta.

Task:     -
RevBy:    -
AutoTest: -
Details:  Add the include path for qplatformdefs.h to the fot.

Task:     -
RevBy:    -
AutoTest: -
Details:  (Only outputs them via qDebug().)

Task:     -
RevBy:    -
AutoTest: -
Details:  Actually building only works on unix (since the generator is
hardcoded.) and make is called without any parameters which is wrong.
A lot is missing for basic build support, but this is a start.

Details:  Makes the code look better.
