Wikipedia external links cleanup

Dear Smalltalkers,

To make them more up to date and to better represent Smalltalk I just
finished a bit of cleanup of external links on
http://en.wikipedia.org/wiki/Smalltalk, by adding, rearanging and
removing few links:

Added:

- Planet Smalltalk
- STIC

Rearanged:

- www.world.st on top, because it is currently the most up to date and
active Smalltalk entry point
- Smalltalk groups together
- downloadable books on the top


Removed:

- Smalltalk: Getting the Message, primer, tutorial
- Smalltalk information visualization tool
- Smalltalk web ring, Smalltalk products and services
- VOSS (Virtual Object Storage System), database management
- Ottawa Smalltalk Institute (OSI)
- Dolphin Map
- Open Cobalt

Reasons for removal: Smalltalk products don't belong here, Smalltalk web
ring seems dead, I didn't hear for a long time about Ottawa Smalltalk
Institute activity, Getting the message link dead

Best regards
Janko
