EcuEditor Compare Improvements:
 - Overhaul of the compare functionality.  Comparing and colorizing now
works for all tables and axises.
 - Compare table chooser now always display scrollbar.
 - Added new compare options.
  - compare to original: compares current table to the selected table
original value (value from disk or revert point).
  - compare to bin: compares current table to the selected table bin
value (live value or value currently displayed in the table).
 - Added ability to compare to open tables.  This searches through open
roms and finds tables with the same name.  This saves time compared
to going through the table chooser.
 - Fixed the tables and data cells concepts of compareType and
compareDisplay.
EcuEditor Compare Part 3:
 - Simplified compare logic.
 - Comparing bin data now refreshes when compare to values are changed.
  - Possible performance implications.
 - added several checks for changes before updating the bin data.
 - Added tooltips to the compare menu.
Added checks before setting the bin value.
 - Setting the bin value with multiple comparedToTables can cause
slowness.
