This is a hack for now.  Eventually we may be able to move away from using
DebuggerScript.js and InspectorScript.js at all.  Certainly InspectorScript.js
should be able to be re-written as a sky module.  DebuggerScript may need to
remain a script if it needs to be injected as a v8 internal script.

Merge with previous line.

Can you file a bug about this too?  We won't have DIR_SOURCE_ROOT in
production....
