Bringing CSS up to this decade's standards.

Here are some tweaks to the CSS styling for `phpinfo()`, since this really hasn't been touched in almost a decade:

- color codes are shortened (e.g. `#000000` is now `#000`)
- table width is bigger and handled via CSS instead of HTML attributes
- fix so that long INI entries don't make the layout super wide
- bgcolor for "Additional Modules" wasn't set
- the `.vr` class has been removed since I can't find any use of it in the entire source tree
- fixed my email address
