Mercury: major code cleanup and debugging improvements

[jpkenny]

Major cleanup of Mercury environment.

• Removed much of the currently unused sst/macro code, but left some code commented out when it was deemed likely to be useful in the near future (or it would be burdensome to reincorporate it).
• Debugging now works using core output objects and verbosity params gets propagated, including to Hg::App.
• Switched to a single consistent copyright statement.
• Many miscellaneous code improvements.
