The scooping release

This release fixes an important bunch of various issues, many of them related to the database, words testing and the "I KNOW ALL" feature. I would like to address my special thanks to @jzohrab and @Heliozoa for they great support!

Added

• Links to the Discord community (README.md and inc/kernel_utility.php).

Changed

• Renamed connect_mamp.php to connect_mamp.inc.php for consistency with documentation.
• "I KNOW ALL" button becomes "Set All to Known" and "IGNORE ALL" becomes "Ignore All".
• Changed the messages when clicking "Set All to Known" or "Ignore All".
• Uncomplete code linting in bulk_translate_words.php. For phone users, it now properly focuses on the main screen after use.
• Only sentences containing more than 70% of known words are shown were testing sentences. Based on an idea from #53, with contribution of #65.

Fixed

• Left-to-right languages where displayed as right-to-left when checking them, as signaled in pull request #42, thanks @Heliozoa!
• People who didn't fill the URL for Google Translate were seeing deprecation warnings while using using the bulk_translate functionality (clicking in "TO DO" for editing multiple new words). Bulk translate itself is not fixed, but warnings are no longer displayed. Merged pull request #44, from @Heliozoa.
• Multiple fixes to the "I Known All Words" feature. Great thanks to @jzohrab!
  • Setting all words to well-known was resulting in a crash when no words were added as well-known (all_words_wellknown.php).
  • Setting all words to well-known was resulting in a crash when multiple words had the same lowercase value. See issue #46!
  • Words were not updated in the view unless reparsing the text (#48). Merged pull request #49.
• In the main dropdown menu, the option "Text-to-Speech Settings" was still leading to tts.php (now text_to_speech_settings.php). Merged pull request #51, thanks @jzohrab.
• Database backup/restoration:
  • Fixed database backup, signaled in #55.
  • Fixed the database restoration, apparently broken since 2.0.3-fork. Pull request #56 by @jzohrab.
• Sentences with unknown words were showed in test when it was not supposed to be the case (#52 and #64).
