A custom subclass of QDoubleSpinBox was created to accept "." and "," as decimal separators.
DoubleVal validator was deleted from the code as it has not being used.
This commits adds the capability to design quarter-wave series and shunt attenuators
A feature for synthesizing transmission lines with lumped components (lowpass form) is also added.

The QLineEdits used for the design input were replaced by QSpinBoxes. It seems to be more convenient and fluid since now the user only need to move the mouse wheel over the input to see how the resistor values move
It was added a checkbox in the qucsatenuattor UI in order to let the user to attach a SP simulation component to the attenuator circuit.
Resistive attenuators are wideband circuits so the GUI doesn't ask for a frequency sweep.
The tool sets the SP sweep to 50MHz-3GHz. If needed, the user can change that before running the simulation.
Compiled without Qt3Support.
Testes on a Mac. I'm not sure about the menubar space.
It also doens't update the layoutsize when changing from
Bridged Tee to Tee, only when go up to Pi again.
* qucs-attenuator/qucsattenuator.cpp (slotSetText_Zin):
Synchronized Zout and Zin when specifying a bridged-tee.
* qucs-attenuator/attenuatorfunc.cpp (Calc): Fixed computation
routine for bridged-tee topology.
