A growing number of application support CMD18 READ_MULTIPLE_BLOCK and CMD25 WRITE_MULTIPLE_BLOCK. This patch adds support for CMD12, CMD18 and CMD25 to libspectrum's mmc.c
Most of the programmes (I've seen so far) utilising CMD18 and CMD25 seem to expect Z-Controller SD card interface, and those appear to be using quite a lot of SPI mode commands. Next revision of the patch, adds basic support for CMD16 and CMD59.
