Fix accessibility issues for keyboard-only users, and fix some Safari bugs (#268)

Also fixed a couple of Safari-specific bugs. Summary:

- Added a secondary-accent ring around buttons on focus. (White didn't show up very well against the background.) We can always chat with design about this later if we want to change it.
- Fixed the weirdness with tabbing over the headers on the Advice pages. I also made the header flex vertically on mobile screens - this fixes the issue of extra whitespace on the right side, and is also somewhat consistent with the menu-y thing at the top of the mobile Meet the Team page.
	- I was very tempted to do this on the Events term archive pages as well, but I figured I should get someone else's opinion on that first.
- Removed the extra triangle symbol in the MiniEventCard on Safari. I had to use a vendor prefix, but if anyone else can come up with something better, then please do that, thank you.
- Stopped the home page "Computer Science Club" from breaking into two lines on small desktop screens.
- Added extra space to mobile footer.
