Serious changes

These are some breaking changes that we've been iterating on in the last few months.

* attributes are more clear in their names
* get the solr version from the tarball url
* update to rbac 1.0
* easily apply more filters to text indexes when using sunspot schema
* helper scripts
* bind to private ip addresses (still need to refactor this to use ipaddr_extensions, which is more solid)
* jvm memory settings
* etc... more little changes

I would not just upgrade this cookbook, because there are definitely breaking changes. We've found them useful, though.
