ctest - filter and run any test

Hi,

Right now, only googletest/qttest/quicktest/boosttest are handled by the qtcreator interface.

Generally a project contains others types of tests (e.g. python scripts, unittest, etc.). It is totally valid and it works, to add them to ctest with add_test in cmake.

If would be nice to be able to see and select them in the qtcreator interface, and to run them.

Even if the results are not understood by qtcreator and cannot be decoder in the console.

Right now, you don't even know they exist from inside qtcreator.

Thanks.
