[PD] data structure setsize allocation

I think there may be a memory leak regarding [setsize] and your new text field. The user is initializing and potentially populating many t_binbufs through word_init after they enlarge an array with [setsize]. But if they set a smaller size with [setsize] it doesn't look like you are freeing those t_binbufs.
I noticed this while reworking your old DT_LIST field to create canvases as data fields. I do [struct test canvas foo bar], which reads an abstraction name bar.pd (if it exists) into a binbuf associated with the corresponding struct. Then when I create a scalar, it evaluates that t_binbuf which creates a hidden toplevel "bar.pd" canvas. The fun comes when using the "canvas foo bar" field in a template for an array field-- then I can use [setsize] to create a massive number of abstractions at once. But when I decrease the array size my abstractions linger until I "vis" them and close them.
So I'm guessing it's the same problem with DT_TEXT, no?
