Installation and troubleshooting docs

[Jim Gallacher <ji...@jgassociates.ca>]

Since there doesn't seem to any movement on our request to ASF 
infrastructure for our wiki, and after seeing yet another thread of 
installation woes on the the user list, I'm thinking we should at least 
buff up the installation and trouble shooting section of the docs. It'll 
be a race to see which comes first - our wiki or a 3.3 release. :)

Any volunteers to comb through the mail archive and throw together a 
coherent document? Plain text is fine - I can LateX-ify quickly enough.
