Add clear option to autoclothing that will unset a previosly set order

[LightHardt]

These changes aim to handle #5366. Updated documentation to alert users of new clear option that will allow them to unset a previously set order. This probably could have been a little cleaner if I added the clear at the end however I think putting it as the first parameter makes it read quite well. Compiled and tested on windows. Please let me know if there is anything I need ti change/do!

I have a lot of grouses with this code, but most of them are from code already there, and this PR doesn't make it worse and actually addresses the open issue

I also note that brace placement is inconsistent with our typical house style, but the original code was inconsistent so I can't blame the proposer for doing the best they can under suboptimal circumstances

Gonna have to put this entire tool on the "needs refactor" list

In any case, changes approved

Yeah looking at it definitely not the cleanest code thank you for the insight. I looked over it again and missed adding the validateMaterialCategory function to the parameter check for the clear case after work or maybe around lunch will be able to make that hopefully final change.

Needs changelog, otherwise lgtm

Last CI failure was probably because I was in the middle of a release when CI ran.
