Several new special nodes

- A set of nodes for building complex strings in a string buffer; to reference the string buffer anywhere a string is expected, you can use -8 as the string number
- A node to pause the action for a specified period of time
- Nodes to alter traits, action points (only in combat), and PC/monster names
- Node to create a new level 1 PC with a specified race, name, graphic, hp, sp, basic stats; custom graphics supported too
- Nodes to test for deadness, spells, alchemy, and status effects
- Node to centre the view on an arbitrary space
- Node to lift the "fog of war", which currently means the unseen and light masks (which can actually be disabled in preferences anyway)
- Node to edit maps (ie, specify which areas are explored)
Changes to existing nodes:
- All the rectangle nodes that affect terrain now work outdoors.
- Play sound node now has an asynchronous option
- Fix min and max modes being swapped in the check statistic node
- Select PC now allows restricting to dead PCs or to PCs with free inventory space
- Select PC now calls the "on cancel" node if a non-interactive selection fails
- Affect deadness node now allows: setting/clearing the "fled outdoor combat" flag; setting/clearing the "absent" flag used for splitting the party; (un)deleting a PC
- If context node can now check if the party is in a specific boat/horse as opposed to any boat/horse
