Correct some non-optional US spellings.

[Moderocky]

Description

When some syntax was added, it was overlooked that its patterns only supported americani(s|z)ed spellings.

Usually, Skript is pretty good at spotting these. This mainly occurred in syntax merged from addons (e.g. bi0aq's vectors) where some things weren't scrutini(s|z)ed in the pull request.

I'm still looking for the other hidden offenders.
I've added the non-US spellings for the ones I found, but if anybody sees any others (I'm sure there are) please feel free to include them.

Common ones include:

• No 's' option in -ize words (e.g. normalize, synchronize.)
• No 'c' option in noun forms of -se words (e.g. advise, practise, license, etc.)
• No British 'u' option in -or words (e.g. color, favor, etc.)
