igs/igs_m027.cpp, igs/igs_m027xa.cpp: Miscellaneous improvements:

* igs/igs_m027.cpp: Added memory clear switch to clear memory contents
  when power is removed (hard reset with the switch on to clear NVRAM).
* igs/igs_m027xa.cpp: Got rid of hopper from Crazy Bugs (V103JP) since
  there appears to be no way to use it and exposed hopper switch as a
  user input so it can still be tested.
* igs/igs_m027xa.cpp: Got rid of third bank of DIP switches from Crazy
  Bugs (V103JP) as comments indicate it isn't physically present
  (although it is displayed in the input test).
* Use mnemonic short names for clones.
