Get the edit monster abilities dialog all working and updated (except for editing individual abilities)

Game changes:
- Remove support for playing a sound and displaying strings when a monster is first seen, since these behaviours can easily be obtained by using the special node called in the same context.
Dialog engine changes:
- Support for changing the font size of LEDs
- When setting the page, a stack now applies a default value if the map is missing the required data
- Add utility "addPage" method to stacks
- If reducing the page count means the current page is deleted, a stack now switches to the last page
