- Cleaned out some of the compiler warnings in the scenario editor (removing unused variables mostly).

- Finally removed the grow box in the corner of the scenario editor window.
- Changed #include <iostream> in several headers to #include <iosfwd>, since they were only present for the use of
  the ostream and istream classes, and cout/cin were unneeded.
- Changed bool to Boolean in the old structs, since that's what it was originally.
- Small changes to graphtool, including an overload of get_custom_rect.
- Added gcd function to mathutil; was needed for something in the new dialog engine
