Sam Atkins ad59fb7cf0 HackStudio: Make Editor ask Debugger if a breakpoint was added/removed
Rather than adding/removing a breakpoint indicator, and then telling the
debugger about it and hoping it works, let the debugger tell us if it
succeeded and then use that to update the indicator.

This prevents the user from adding breakpoints to invalid locations
while the debugger is running. It also avoids a couple of scary
VERIFY()s. We still allow creating breakpoints in invalid locations
while the debugger is *not* running.
