Please add me to SolrWiki contributors

[Gaurav Kumar]

Hi
I am working on writing some open source tool for Solr Camel component, it 
would be great if you can add me to list of contributors.
Also I realized that you guys have upgraded the wiki to Solr 5.3, but we are 
using Solr 4, and suddenly now there is no information available for the older 
version.
Is there a way you guys can keep information about previous versions as well?
