Character Flags and Item Stubs

Today, I expanded Master Leo's dialog.

Specifically, the parts concerning quest giving.

I have character flags to check for whether or not do display a dialog choice.

Those choices can now set (or reset) those character flags.

And I'm part way to having items.

They exist in the world, and they can be associated with dialog choices.

Next up is to make the dialog choice give the item to the character.
