[Debugger] Inspector needs to watch for step events.

[anevilyak]

Currently, if one has the inspector window open, but then causes a thread to take a step, the inspector will be completely oblivious of that fact. Consequently, if the executed instructions modified data within the block currently being inspected, those changes won't be reflected, and in fact, the only way to cause the displayed data to be refreshed is to either jump to another block and back, or close the window and re-inspect the address.

This is less than ideal, and as such, the inspector should watch for the relevant team events, and force a block refresh when one of them occurs.
