Include <cmath> so abs(float) can be found

During the exp-run in bug 208158, it was found that x11-toolkits/wxgtk30 gi=
ves
errors with libc++ 3.8.0 [1]:

./src/stc/scintilla/src/Editor.cxx:5844:6: error: call to 'abs' is ambiguous
        if (abs(pt1.x - pt2.x) > 3)
            ^~~

This is because pt1.x and pt2.x are float values, but <cmath> is not includ=
ed,
and abs() for float values comes from that header.  Fix it by including
<cmath>.
