Pull the class OutputSettings out of the class ProjectRenderer so that it can be used in other contexts as well. Also move the enum ProjectRenderer::Depth into the new class OutputSettings and rename it to BitDepth. Adjust all places that referenced ProjectRenderer::OutputSettings accordingly. Adjust the two places where an instance of OutputSettings is created: the main function and ExportProjectDialog::startExport. Store an instance of OutputSettings in AudioFileDevice and remove several members and methods which are now replaced by this instance. Add a getter for the OutputSettings to AudioFileDevice. Storing an instance of OutputSettings in the base class AudioFileDevice enables the simplification of the following constructors and general code in the following classes: * AudioFileDevice * AudioFileOgg * AudioFileWave Because OutputSettings contains everything related to sample rate, bit rate settings and bit depth these parameters could be removed from the parameter list of the aforementioned constructors. Simplify the signature of the factory method AudioFileDeviceInstantiaton (defined in AudioFileDevice.h) and reorder the parameters by significance. Move the logic of how the minimum and maximum bitrate is calculated using the nominal bitrate into AudioFileOgg::minBitrate() and AudioFileOgg::maxBitrate(). Previously this was defined in the constructor of ProjectRenderer where it does not belong as it an implementation detail of the OGG export. Remove the code that converted the bit depth enum to an integer from ProjectRenderer as it is now solely represented as an enum. Remove class members for the minimum and maximum bit rate from AudioFileOgg and adjust the code in the implementation to use the values stored in OutputSettings.
