IDE: Read multiple sectors when possible #54

Currently, reading from the IDE drive reads sector by sector, which is really slow. Some performance improvement can be reached from reading more than one sector at a time.

The file_read method on FAT files is not designed to work correctly with this design... The cache blocks are only one sector long.
