... by eliminating images containing text.
of course, this causes some stylistic issues. oh, well.

We didn't update the dependencies model in case a project gets loaded or
unloaded. (Or the session switched.) In that case we do a rather drastic
reset() now.

We used to restore to the wrong BuildStep if we couldn't find a factory
for a build step. Unfourtanetly that's exactly what a 1.1 project
loading a 1.0 project does. So some settings are lost.
This fixes that.

Qt Creator wouldn't find the correct target if shadow building a project
that uses $$OUT_PWD, like for example itemviews-ng.
We didn't set the necessary variable on the ProFileReader *, simplified
the code to always use a ProFileReader created for the exact
profilenode.

After all I don't need all that stuff in the cmakeplugin, all i needed
is now bundled in debugginghelper.h/cpp
