    gedit-plugin: add <Shift>F2 to search codesearch.debian.net
    
    This new action will perform a regex search on
    codesearch.debian.net to find the source definition of
    the function/macro at cursor.
    
    Primarily targeted at C code, function definitions are
    expected at start of line and macro definitions expect
    "#define".
