There are situation where adding multiple queries is super beneficial. 

This PR enables package users to call `$search->addQueries(...)` in two different ways.

#### Single dimension array parameter

In this case an array of `BuilderInterface $query` are passed to the root `$search->addQuery()` function.

#### Multi dimensional array parameter

In this case an array of arrays is passed in, each member of the array is to match the function signature of `$search->addQuery()` and the PHP 5.4 traversable unpacking language feature is used to parameterise the root `$search->addQuery()` function.

'_source_exclude' and '_source_include' was missing in parameters whitelist.

* bump development version number

* add scroll to URI parameters, fixes #201

* remove deprecated queries

* move tests

* added support for 5.x elasticsearch syntax

changed script_score lang to painless

* refactored tests to support elastic 5

* update changelog

* uri parameters was moved to container, introduced 5.0 new request body parameters

* removed filter endpoint, change order for query and postfilter

* search test has too many not necessary test cases

All those tests has to be in specific query or endpoint. Also functional tests make more sense then asserting it in the SearchTest

* moving elasticsearch/elasticsearch to required dependencies

Also removed unused imports

Suggester namespace was removed in commit
832934df.

from now, if there is only one query set, there will be no more generated bool query. Also Query class from now on is absolutely not necessary. There is no BC breaks.
