Tracking issue: new debugger features

[LukasKalbertodt]

Cool features of the debugger:

• Event view:
  • Scrolling
  • Filtering
• ASM view:
  • Scrolling
  • Set breakpoints by clicking on instruction
  • Show arrows to destination when hovering on jumping instructions
  • Show comments with additional useful information (like when using an IO register: which register?)
• Manipulate data when debugger is paused
  • flags
  • registers
• Show more data:
  • The stack
  • PPU
  • Sound
  • Interrupt
  • The whole memory (as popup presumably)
  • The last 10 addresses where we came across a jump-like instruction
• New ways to pause the emulator:
  • Pass breakpoints via CLI
  • When a value somewhere (registers, memory, ...) has changed
  • When a specific instruction is executed
• More controls
  • jump to end of function (run until RET or RETI reached)
  • run until any jumping instruction is reached
  • execute N instructions
• Make data in CPU/PPU/... views bold (or something) if it changed in the last instruction

(Feel free to edit this comment if you want to add new features)

Note that this is a very extensive wish list and I doubt we will ever implement all of those (probably not even half of it).
