added functionality that exits a dialog box when the dialog has reached the end
created a simple dialog function that will bind a regular data file to an object without the need for a lot of boilerplate
added interactivity on the statue, as well as trimmed down the content for the mailbox
fixed a bug where the player's direction would not change when against a wall
fixed the statue's target box
hid the interactive object highlighting. this is still useful for designing new areas and objects, but doesn't need to be on at all times
added support for multi node dialog digraphs. only single-option nodes are supported for now, but each node will move through the sequence and display
changed how the dialog files are loaded so that one file can have multiple dialog digraphs. this reduces headaches that would occur with a large number of extremely simply digraphs in a region. previously, each one would need its own file, now they are all in a single file
