version 0.91: lasers, multiple

version 0.91: lasers, multiple

+ LASERS!!!! four pickups and youll fire laserbeams instead of bullets
* multiple enemies can be hit at once, very usefull when firing lasers
+ MULTIPLE!! like the (shadow)multiple from MSX-Nemesis. for 5 pickups
  you get an multiple following you, firing bullets & lasers like you
* most data (enemy positions) stored at TEXT_MEM & DELC_LEN positions
  instead of in program, saving A LOT of bytes in program-size
- at release of 0.91 bullets didn't work, laser is used instead
