fix version string on config.h.cmake

It was messing up with version string on project files.
add bsim4v30 to cmake
removed module.cpp, it has been put there by accident, belongs in qucs-core
Merge branch 'master' of ssh://git.code.sf.net/p/qucs/git
Fixed fontmetrics, throughout qucs it was taken from QucsSettings.font. that way the scale was ignored.
fixed displacement of cursor while drawing paintings
