DATAMONGO-1228 - Release version 1.8.0.M1 (Gosling M1).

Removed EvaluationExpressionContext from all AbstractMongoQuery implementations that don't actually need it and from AbstractMongoQuery itself, too. Cleaned up test cases after that.

Moved SpEL related tests into AbstractPersonRepositoryIntegrationTests to make sure they're executed for all sub-types. JavaDoc and assertion polishes.

Original pull request: #285.
