v0.49

### Version: Exet v0.49 August 7 2021 - Update the lexicon to a new version, adding CMUdict pronunciations. - Add Homophones and Spoonerisms! - Rename the "Del+subs" tab to "Edits + 🕪" and make it show both edits (substitutions, insertions, deletions) as well as homophones and Spoonerisms. - To the tops of charades, edits, and homophones/spoonerisms sections, add a text input field where you can make changes to the entry, possibly to try out alternatives. Hitting escape in the field will restore the value taken from the grid. - Sort the Edits results by a form of edit distance (substitutions count for max(plus-length, minus-length)). - Minor code-cleanup (more semicolons, mostly).
