Fix invalid date error in Safari
Add base code for simplified jQuery
Add more functions to `$`

- `attr`
- `closest`
- `each`
- `length`
- `replaceWith`
Move `$` to under the `jews` definition
Make `$` function and ignore `window.$`
Add `$.matches` and `$.closest`
Make `closest` return itself for method chaining
Add `hasClass` to `$`
