8.1

• Adds documentation for es-aggregate.pl and App::ElasticSearch::Utilities::Query
• Adds tests for App::ElasticSearch::Utilities::Query
• Fixes the handling of minimum_should_match parameter.

This code now does the right thing:

my $q = App::ElasticSearch::Utilities::Query->new();

$q->add_bool( should => { term => { foo => 'bar' } });
$q->add_bool( should => { term => { bar => 'baz' } });

$q->minimum_should_match(1);

Tests in place to make sure it does in the future too!
