5.0 build 288 - Hotfix

Hotfix for some bugs (one new, one old)

Bugfixes

• @Vankka helped fix DiscordSRV Extension not registering
• All Platforms should now use newer MySQL driver that is inside Plan. This should fix incompatibilities with MySQL 8 (for example fix "Unknown system variable tx_isolation")

I did not test the MySQL 8 compatibility because having 2 different mysql installations is cumbersome, let me know if it works (Tested with Mariadb 5.6).
