Remove release checker, fix settings screen scrolling

Release checker removed -- DNS MITM blocks all outbound DNS
including to GitHub, and raw UDP bypass didn't work on Switch.
Removed curl/jansson/mbedtls dependencies.

Fixed settings screen not scrolling when items overflow the
visible area. Added clip rect and auto-scroll to cursor.
