0.8.1 "Advanced Junkyards and Janitors"

This release fixes a bug with word wrapping that was especially annoying in the last release, has a minor fix to behavior when adding multiple atlases to a Font, allows SDF fonts to work with emoji (mostly), adds the massive SDF pan-unicode font Go Noto Universal, and also adds a new {CANNON} effect. Something is almost assuredly still incorrect here, but outside of known bugs in the README, nothing so far is absolutely broken, so... this looks good to me?
