Add new functionality to "Change signature" refactoring

Extract single point of entry for all change signature refactorings and fixes (remove parameter, add parameter) Change signature now affects overriding functions as well Ask the user whether he wants to refactor base function(s) or the selected one if appropiate Fix a problem with descriptorToDeclaration in JetChangeSignatureHandler Rename: JetFunctionPlatformDescriptor -> JetMethodDescriptor
