UI: Add random splashes to loading screen (#128)

This PR introduces splash text messages that change per startup on the loading screen after selecting a game. It also moves the "RYUBING" logo splash in logs to be inside its own class, which also handles loading screen splashes and titlebar splashes. Credits to VewDev, Lotp, Sh0inx, yell0wsuit, and Greemdev for pointers and assistance throughout this PR.
