Summon Command Acts like Magicite

following from the above..

- have the C2/19C7 table entry go somewhere new, where you do: "JSR $37DC / STA $B6 / JMP $1763".
- having MP be untouched for one variety of the Summon command but not the other can be tricky.  if i follow a difference right, hook C2/4D9C, and branch somewhere to set Bit 6 of $B1 before doing "LDA $3344,Y".
