v6.0.1

This is a quick release to (tentatively) address issues users are having with the .dat payload.

• Updated ctrulib (should fix CakeBrah and menuhax 3dsx launchers)
• Fixed bug that could cause a payload being mistakenly launched after creating a new pin
• Minor cleanups

Note for dev branch users: there was a bug affecting exception handlers in this release. Please use the latest commit
