Show memory address on SYM line in emulator debug output

The memory address of the most recent symbol is now displayed next to
the name of that symbol in the emulator debug output, to make it easier
to see how close the program counter is to that symbol.

The source location of that symbol is now also shown as dimmed to make
it less distracting.
