0.5.1 "Super Effective"

This release adds a lot of TypingLabel effects, and improves the support for what custom effects can do. The new effects are now visible and documented on the Tokens wiki page. They take advantage of the new ability to smoothly scale individual glyphs, and also to specify rotation per-glyph in an effect. Other than the effects, this is a minor release, and only some small bug fixes have been added (relating to size-changed or rotated text).
