hosts(opts={}) returns incorrect values when a host is passed through

In the autocomplete branch it looks like the code that works out what glob to use for looking up hosts is wrong in rrds.rb

I used the following;

    def hosts(opts={})
      hosts = opts[:hosts]
      case hosts
      when String && /,/
        glob = "{#{hosts}}"
      when Array
        glob = "{#{opts[:hosts].join(',')}}"
      when String
        glob = "#{hosts}"
      else
        glob = "*"
      end

      Dir.glob("#{rrddir}/#{glob}").map {|e| e.split('/').last }.sort.uniq
    end

Note the added "when String". This will make /data/ return the correct metrics for a given host.

Looks fixed now :D
