As of rP19270 the randInt function got depricated, but wasn't removed since it was still used in the rms. Following commits (rp19355 rP19433 etc.) removed most instances of randInt, this commit nukes the last bit in Unknown* and newly added ones...
As all instance have been removed the old function and the random.js file can be removed. Notice some wiki pages need to be adapted since they mention this file:
