 - maximum range for Cut Z is now zero to deal with the situation when using V-shape with tip-dia same value with cut width
 - modified QValidator in FCDoubleSpinner() GUI element to allow entering the minus sign when the range maximum is set as 0.0; also for positive numbers allowed entering the symbol plus
+- made sure that if in Gerber UI the isolation is made with a V-Shape tool then the tool type is automatically updated on the generated Geometry Object
