Changes to improve solr template

- Fixed typos on deploy-solr.rb and rubber-solr.rb
- Removed base template dependency to avoid overwriting the base files (rubber-yml, etc.)
- Updated jdk and tomcat mirrors
- Added examples to the variables on rubber-solr.yml
Adds a template for solar using the sunspot gem that makes the installation of solr trivial

- Adds gem dependencies for sunspot
- Adds a new solr_sunspot role
- Adds capistrano tasks for start, stop and reindex
Fixed common file template to use solr_sunspot instances instead of solr instances
Added openjdk as a library dependency to avoid having to download a separate jdk file
The create_master_db script needs to delete all blank users initially

Deleting `user=""` where `host="localhost"` doesn't seem to be enough, because deploying a new app with a different hostname will not have a host that is *literally* `localhost`

Add missing 'nginx_log_dir' setting to rubber-passenger_nginx.yml

#320 added a 'nginx_log_dir' setting to specify location of the Nginx log directory, but didn't add the new setting to all related yml files. I looked through the templates and I think that rubber-passenger_nginx.yml is the only other yml file effected.
