This adds very simple support for storing BMP files with BITMAPV3INFOHEADER and BITMAPV4HEADER. This in turn allows us to store alpha channels which is nice for our .pp file format. For the moment no data regarding colorspace is saved, only the bare minimum to make a valid file. Some small restructuring of the code is made to hopefully make it easier to implement more DIB-headers and support for colorspace/gamma correction in the future.
