Fixed a bug where the effects of (enchant:) were temporarily suppressed whenever a (dialog:), (prompt:) or `(confirm:)` was run at roughly the same time. This isn't the fix I wanted to make (instead I'd rather it only call updateEnchantments() when it explicitly needs to), but it'll have to do for now. Also fixed a bug where the Styles panel of The Harlowe Toolbar didn't preview animations correctly. Closes #203.
