Aesthetic and wording changes

- Restored original frame code so that we have a black border (easier to
  see pictures) and height not always maximizing (which was causing the
  web page to be unnecessarily tall).
- 16:9 ratio
- Slowed slideshow speed to 6 seconds, which is more ideal for actually
  looking at the pictures (generally slower is better)
- Edited wording of front page
- Small edits to about us page (and removed link to itself)
- Fixed some missing </p> tags and indenting
