Want to scale down Install guide a bit...

[Glen Mazza]

Hi Team, presently we document four servers in our Install guide: 
Tomcat, GlassFish, JBoss/WildFly, and IBM WebSphere.  The first two I've 
updated and I plan on doing WildFly next, but I'd like to get rid of the 
last one, I have no intention of personally downloading & running 
WebSphere and I don't think anyone else will as well. I think three 
servers are more than enough for our limited team, and we'll always have 
the documentation in the 5.0.1 guide if somebody needs it. WDYT?
