CMI Plugin Documentation

Will update personal CMI documentation here

Notes:

I was looking at perms and saw admins have access to cmi.interactivesign.*
the regex is wrong on default. config.yml > InteractiveSigns > SignRegex: ([ic:([a-zA-Z0-9-]+)]) # was missing dash after 9
- < ^ this is new updated line in case goes bad again, it was able to find the ic name i was using ^>
