Don't presume there are settings for all sections.
Adding < and > to escaped query characters.
Add a common configuration section.

Some new 2.2.1 settings were incorrectly added to the indexer section.
Setting these keys requires a new common configuration section. The
following keys were moved to this new section:

lemmatizer_base on_json_attr_error json_autoconv_numbers
json_autoconv_keynames rlp_root rlp_environment rlp_max_batch_size
rlp_max_batch_docs

See http://sphinxsearch.com/docs/manual-2.2.1.html#confgroup-common for
more information.
Merge pull request #82 from trevorsmith/common-configuration

Add a common configuration section.
Add a common_sphinx_configuration setting.

A new "common" configuration section was added in Sphinx 2.2.x containing several settings formally located in the "indexer" section. To maintain backwards compatibility with older versions of Sphinx, the new section will be disabled unless common_sphinx_configuration is set to true.

Remove database apt-packages for Travis.

MySQL one's already covered, PostgreSQL one is no longer valid.
Use the default Sphinx versions Travis provides.
Run the tests on MRI 2.0.0 and 2.1.0.
Ensure binlog_path is set for tests. Makes Sphinx 2.2.x happy.
Messages are binary, so let's set the spec encoding appropriately.

Add a common_sphinx_configuration setting.
Hold onto address and port when crafting listen, but don't render them.
Ensuring lemmatizer_base is a setting for indexer/common.
Riddle::Query.escape covers = and & characters.

While they don't raise exceptions when used outside their expected roles, they are part of the extended query syntax, and so I guess they should be escaped (the purpose of this method being to nullify extended query characters rather than avoid syntax exceptions).
Updating HISTORY.
