Memory dump with label support in debugger.

[hach-que]

The debugger should accept:

> inspect memory labelHere
> disasm labelHere

The inspect memory labelHere should show the memory from the specified label until the next label, unless a second parameter is specified (which can be either a length number or a label) in which case it stops appropriately at that point.

The disasm labelHere should disassemble from the specified label until the next label, unless a second parameter is specified (which can be either a length number or a label) in which case it stops appropriately at that point.
