Porting a disassembler

• 1: Porting the DARM disassembler
  Porting an open source disassembler to RISC OS - converting it to C89 and building a simple Debugger module.
• 2: Adding *MemoryI and *DumpI
  The *MemoryI command allows live memory to be disassembled. The *DumpI command is the equivalent, but for a file.
• 3: Adding *InitStore, *Memory and *ShowRegs
  The *InitStore command fills application space with a constant value. The *Memory command dumps memory regions. The *ShowRegs command will display the registers from the last abort.
• 4: Fixes, CI and *MemoryA
  Fixed some syntax help messages, and error messages. Added the automated builds in GitHub through the RISC OS build service. Implemented the *MemoryA command to alter memory.
• 5: Breakpointing (first part)
  Adding the *BreakSet, *BreakClr and *BreakList commands. Added the beginnings of a Prefetch Abort handler.
• 6: Breakpointing (second part)
  Finished the Prefetch Abort handler, and added *Debug, and *Continue. Tidied up some of the disassembly operands.
• 7: Tidying up output (first part)
  Continuing tidy up of the disassembly - LSL and friends, SETENV and TEQP were made tidier. Started looking at disassembly problems with MSR and MRS instructions.
