Issue #8206: Incorrect XHTML results

Changes:
- Change TooltipManager back into a singleton
- Give the OutputList object a unique output id
- Increment the id at each startFile() atomically
- Pass the id to the HTML code generator
- Store tooltips per output id.
- Keep track of tooltips that are already written for a given id
- for output formats other than HTML the output id is 0 and tooltips are
  not collected and written
