First working edition of the CalChart ghost viewer.
This allows you to view sheets behind the one that you are working on.
Added some comments to make this easier to review.
Fixed a bug with dot and text colors. The application was using dot colors
for text colors.
Update cc_preferences_ui.cpp

I had made a change to the preferences to make sure that the colors reset on "Reset All" - I didn't carefully consider this change though, so I don't want to keep it in as a permanent fix to that issue.
Update cc_preferences_ui.cpp

Just making the preferences file identical to the original.
Updates: making ghost_module behavior an enum based parameter.  Removed ghost_source and ghost_tool.  (enforcing my coding style, sorry :)
