Since the actual tool chain is defined in the project, it
moved there from the qt version.

An empty default make target lead to an error.

Doesn't do anything else than showing the tool chains yet.

QtVersion provides possible toolchains that can be used by the
Qt version, e.g. winscw, gcce and armv5 for symbian-abld.

Passing the Project to the tool chain now. Not quite sure if I like it.

At the moment you need to close and reopen the preferences dialog though.

Will be used to find the "Qt in PATH" and "Qt from Symbian" versions.

For example when you typed Ctrl+l and find that you don't want to use
the goto line filter after all.

Bad idea to hardcode the background color. Now using the style directly
to draw a fake tooltip as background for the function argument hint.

This will result in a speedup.
