- Got the new dialog engine into a semi-functional, mostly crash-free state!

- Created constants for the number of monster and terrain sheets, so that we can easily add more.
- Added init_sheets() function to initialize cPict's static variables.
- Moved the code for checking for an interrupt key out into a separate function so that it can be used elsewhere as well.
- Added error checking to make sure a sheet exists before drawing from it. (Note: Will need to catch the exception and draw a blank rather than simply terminating.)
- Fixed bug where status icons were drawn instead of terrain map icons.
