StudioWelcome: Make the hidden splashscreen recoverable

The user choice made on dialogs with a "Don't show/ask again" checkbox
should be resettable via the "Environment->Interface->Reset Warnings"
setting.

This patch let's the StudioWelcome splashscreen use the dontshow/reset
mechanism of CheckableMessageBox for that.
