Integrate batch processing into the standalone Corona Image Editor

The batching ability of the Command line corona image editor is useful. However having to save the postprocess conf files, edit the BAT file and stuff like that feels unnecessarily complicated and it would be far simpler if there was a way in the CIE to just browse for a folder and have corona work through each of the CXR files using the settings applied to the currently open CXR. It would just be much more user friendly. Even if its still using the command line tool behind the scenes, not having to edit the config files or the bat file and having some sort of progress readout would be useful.
