Rename A!, A@ and A, to C!*, C@* and C,*
Also, rename "Addressed devices" to "Indirect memory access". I do this because I need to add indirect versions of !, @ and , to allow boostrapping directly to EEPROM and that A,, thing I've added to assemblers felt like really bad names. With this change, I'd like to generalize the use of the * suffix for aliases.
