Marvellous Inc. v1.4.1

A few bugfixes on this update, all related to custom levels. Changelog: - On custom levels, different test cases generate different values of random numbers (but consistently the same numbers on the same test case) - Custom level emails don't show up as not-completed anymore - Show custom puzzle errors on startup. That means if you're writing a level and it is badly formatted, you will understand why instead of it simply not showing up. The process is still not as smooth as it could be. - It is now possible to access the index of the test case being ran on your custom puzzle using the TEST_CASE constant Carry on fellow employees
