Update to v106r17 release.

byuu says:

Changelog:

  - tomoko: the library menu is now called the systems menu (even in
    code)
  - tomoko: added icons to menus (disambiguates systems menu entries)
  - icarus: added missing .ws, .wsc extensions to scan dialog search
    list
  - higan: added Benesse - Pocket Challenge V2 emulation¹

¹: the Benesse - Pocket Challenge V2 is a WonderSwan (ASWAN) SoC
inside a custom designed shell. Games made for the WonderSwan (mostly)
run on the Pocket Challenge V2 and vice versa. The big difference is
that the Benesse has a different number of input buttons, that are also
named differently. Of course, right now, I don't know what the buttons
are named or where they're mapped on the 16-input keypad matrix I/O
port. It's also possible that the internal EEPROM doesn't exist, it
definitely has a unique (and also undumped) IPLROM, and other things.
The ROMs have their own .pc2 file extension. So it's getting its own
system entry.

What I'm going to do for v107 and above is utilize the new systems
configuration to mark the Benesse as hidden by default from the main
menu. I don't think anyone in the world will actually care or want to
play this, but there was really no reason not to add it.
