Title: fixes #84: allow group_by multiple fields

Fixes #84: allow group_by multiple fields.

To recover grouped values:

search = MyClass.search :with => {:some_id => 85}, :group_by => "user_id, type";
search.context[:panes] << ThinkingSphinx::Panes::AttributesPane
search.each do |item|
item.sphinx_attributes[‘count(*)’] # count
item.sphinx_attributes[‘user_id’]
item.sphinx_attributes[‘type’]
end
