This also temporarliy disables linting '.ts' files due to the fact that the currect '.d.ts' files contain too many errors/warnings that need to be manually fixed, but since I'm going to be rewriting the whole module in TypeScript anyway, resolving these ESLint error's is a pointless waste of time.
Travis was failing with a weird ESLint error, and when I checked locally, the problem seemed to be related to Vuepress v0. Upgrading to Vuepress v1-alpha seems to fix this (at least on my machine...)
