run "cmake . [...]" if a build already exists in the build dir. this
saves the user from reproducing all the arguments he may need.
on the downside, this will go utterly awry if the source dir of the
existing build is a different one than known to creator. this should be
a rather rare corner case, so ignore it for now. the nice solution would
be a checkbox (on by default) to request this new behavior.
Adds a little bit of code duplication, don't currently know how to best
avoid it, so I'll leave that for now as is. To be tested once Andre
pushes his stuff.

Details: Give IOptionPage an id() to differentiate from trName(). Make showOptionsDialog return a bool (applied) and give it an optional parent. Change Cpp and form class wizards, give them a Configure... button to change those settings.
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.
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.)
