The coplanar waveguide characteristics formulae were incorrect, mainly
due to an incorrect usage of the algorithm used to compute the complete
elliptic integral of the first kind K(); the argument passed to the
function was the elliptic modulus k, while the function was expecting
the parameter m=k^2.
The function providing K(k) was rewritten, in a slightly simpler form,
to accept the elliptic modulus k as input parameter.
The same formulae were corrected in both QucsTranscalc and qucsator.
The Technical Papers document was updated with a short description
of the algorithm used to compute K(k).
* qucstrans.cpp (slotCopyToClipBoard): Added clipboard copy for
new coplanar line types.

* added new lines: coplanar with and without backside metal
