Start the design migration.

Add grunt stuff for automated Sass compiling, begin massacring HTML.
Gulp.
Style post modal, posts, some class switching in JS
Retrofit CSS for the existing HTML
Tag styles, updated tag JS, autogrow textarea added, add tabindex

Add helper classes, develop tag styles, remove legacy stylesheets,
remove some JS (this caused removing tags to fail – to be investigated)
Delete legacy CSS

And hope it doesn’t break anything.
Better specificity when it comes to client/server-side tag removal
Add add tag/remove post buttons & styles, new typography, add taggee names as image titles
Add generic team photo
