Workaround for strange wxPython display error.

Since a while, wxPython has been refusing to correctly display strings with a dash in them in the staticText object. Given a string "xx-yy", only "xx" is displayed. This caused some problems for protocols with dashes in their protocol names. I've worked around it by replacing all occurrences of "-" by "_".
