    Added GBL 'Game Browser' access to the World of Spectrum June 2017 Mirror at archive.org. It is somewhat slower than the current WoS site, but probably more dependable in the future.

Added following Microdrive functions to the GBL 'Game Browser':
- 'Format Microdrive'             SYMBOL SHIFT-1 (!)
- 'Add file' to Microdrive        SYMBOL SHIFT-3 (#)
- 'Copy Image' to Microdrive  SYMBOL SHIFT-4 ($)

    Upon user request, the special function: SYMBOL SHIFT-2 (@) was added to the GBL 'Game Browser', allowing the contents of a physical Microdrive cartridge to be saved to the SD card as a .MDR type image.
    This requires of course that the 'Interface 1bis' is plugged in at the back of an original Sinclair ZX Interface 1. The two interfaces cannot function simultaneously. When the 'Interface 1bis' is in 'Active' state it disables the original, but it can control its IO ports and thus access the Microdrive.
    The record header and data block are treated independently in respect of reading errors, having separate checksums. The number of retries in case of checksum errors is set to (at least) three, but repeating the function attempts to read again the 'bad' blocks only, without affecting the already saved 'good' ones.
