Update README.md

Corrected typo on "Boycotted brands". Changed order of "Boycotted brands" and "Supported brands". Added "Boycott list ..." link. Removed "https://" prefix from "archive.today" to maintain 20 link total in copypasta section, within 8chan OP limit of 20 links. Added ".com" suffix to "donotlink". Changed "User ID" to "Twitter user ID". Corrected capitalization on "Twitter". Removed unnecessary arguments from "The media is finally beginning to see ..." link. Added link for "Ignore derailers and shills". Reworded some sections to clarify and bring character count down. Exchanged three long links in "Articles and blog posts" section, Escapist, Reddit, YouTube links with v.gd short URLs to bring character count down. v.gd preferred over other URL shorteners to minimize character usage and to cultivate user confidence through its preview interstitial. Copypasta section was 2132 characters before changes, is 1790 characters after changes, within 4chan OP limit of 2000 characters.
