#21 Typo in major in CREDITS

Major is written as majour in the credits, I tried to make a PR but I already have a fork of libertybsd-scripts on my profile from a while ago and it interferes with me being able to clone the latest repo @jadedctrl please make my change,

P.S: Thanks for the credit, much appreciated :)

Jajaja, for a minute, I read the topic as "Major typo in CREDITS," wondering how badly I screwed CREDITS.md up. :p

Fixed with 9f8c49c2b9

P.S.: Thanks for the commits :)
