Fix #169 story edit issue with extended unicodes

Fixes

• 🐞 Fix/issue 169 story edit issue with extended unicodes by @fabd in #212
• 🐞 Fix #207 : Unable to close the Edit Story dialog... by @fabd ( fa678c8 ) (site update Sept 8th 2021)

Discontinued

The kanji recognition aka "sight reading" page previously available at /sightreading has been abandoned. It was broken for some time and likely hardly anyone uses it. A decently working rewrite merged in #204 was abandoned in favor of focusing on existing issues and improving existing features.

Changes

• Feature/use vite by @fabd in #196 -- the live site is now deployed from the new Vite build which includes a lot of Javascript refactored code, hopefully no new issues introduced. 🍀

Developer stuff

• Feature/kanji recognition refactor to vue by @fabd in #204 (abandoned but merged useful code changes)
• Feature/update docs installation by @fabd in #211 (should be up to date with the new Vite / esbuild setup)
• Update Installation Instructions by @wildwestrom in #210
• (refactor): remove obsolete coreJson.php by @fabd in #208

Full Changelog: v2021.04.28...v2021.10.14

Upgrade code base to php7.4

Feature/php74 docker and php fixes #194

Php fixes deployed to live.

Web (javascripts) not deployed (no changes).

#193 Tested locally, everything seems to work fine.

Not strictly necessary to update live but may help to catch minor issues before deploying too many other changes.
