#184 fix up ip cameras page

[Nathan Oostendorp]

Gussy up the IP cameras page:

https://github.com/ingenuitas/SimpleCV/wiki/List-of-IP-Camera-Stream-URLs

we need a table with fields:

default IP address
default username/password
MJPG path

We should also add the cameras that we have Trendnet, Edimax, Rosewill etc
