Biggest changes forced by this: alt tags for all images, resulting in new strings added to messages.json, and a new i18n paramter/prop added in a plot of places. Another change of note is that there are two new tslint.json files under ts/test and ts/styleguide to relax our rules a bit there. This required a change to our package.json script, as manually specifying the config file there made it ignore our tslint.json files in subdirectories
