This lets bmpbklk_utility generate BMPBLOCKs with EFIv1-compressed bitmaps. It also adds the ability to display or unpack BMPBLOCK blobs. The compression/decompression routines come from the tianocore EDK on sourceforge and are written in C, so now there's a mix of C and C++, but it works just fine.
