Update Wiki to reflect that all Mr. ChromeBox Coreboot Firmewares should work with cleaned ME

Having cleaned the TXT (I know people refer to it as ME, however Atoms and Celerons, and some Pentiums, utilize Intel's TXT, which is sort of a cut-down version of the ME) on my sister's Acer ChromeBook CB11-131, which runs Mr. ChromeBox's CoreBoot firmwares, and having read that Mr. ChromeBox himself attests that all his ChromeBooks running his firmware work fine after being cleaned with ME Cleaner.
