added two scripts for locale checking

localeCheck.js

+const fs = require('fs');
+const glob = require('glob');
+const path = require('path');
+const chalk = require('chalk');
+const chalkTable = require('chalk-table');

+const localeBase = JSON.parse(localeBaseRaw);

+
+console.clear();
+console.log('---- LOCALE CHECK ----');
+console.log('');
+
+let results = [];
+
+const allLocales = glob.sync(path.join(__dirname, '/src/i18n', '*.json'));
+allLocales.forEach((locale) => {
+    if(!locale.includes("en.json")) {
+        let rawLocale = locale.split("/")[locale.split("/").length - 1];
+
+        let localeNewRaw = fs.readFileSync(locale, 'utf8');
+        let localeNew = JSON.parse(localeNewRaw);
