Internal refactor completed in order to improve tree shaking and dead code removal. The public API, with an exception to ion-slides, has stayed the same. However, internally many changes were required so bundlers could better exclude modules which should not be bundled. Ultimately most changes resorted to removing references to `window` or `document`, or a module that referenced one of those. BREAKING CHANGES ion-slides was refactored to remove the external dependencies, and rewritten in TypeScript/ES6 modules to again improve tree shaking abilities.
