Full editing pass of the Spring Data MongoDB reference guide. I also adjusted index.adoc to work with the changes I made to the build project, so that we get Epub and PDF as well as HTML.
Original pull request: #559.
Inherit fields from previous operation if at least one field is excluded. Extend FieldsExposingAggregationOperation to conditionally inherit fields.
Backport to Java 6 code.
Original pull request: #538.
Remove client side operating system check as operating system-dependant constraints depend on the server. Add check on whitespaces. Add author tags. Extend tests. Extract database name assertion in an own method.
Original pull request: #546.
Remove DateFactory and split up tests.
Introduce dedicated Timezone abstraction and update existing factories to apply the timezone if appropriate. Update builders and align code style.

We previously used MongoTemplate.insertAll(…) which determines the collection to insert the individual elements based on the type, which - in cases of entity inheritance - will use dedicated collections for sub-types of the aggregate root. Subsequent lookups of the entities will then fail, as those are executed against the collection the aggregate root is mapped to.
We now rather use ….insert(Collection, String) handing the collection of the aggregate root explicitly.
We now use _id lookup for remove operations that query with limit or skip parameters. This allows more fine grained control over documents removed.

We now use AbstractMongodbQuery.fetch() instead of AbstractMongodbQuery.fetchResults() to execute MongoDB queries. fetchResults() executes a find(…) and a count(…) query. Retrieving the record count is an expensive operation in MongoDB and the count is not always required. For regular find(…) method, the count is ignored, for paging the count(…) is only required in certain result/request scenarios.

Move method from AggregationCommandPreparer and AggregationResultPostProcessor to BatchAggregationLoader. Extract field names to constants. Tiny renames to variables. Add unit test for aggregation response without cursor use.
Original pull request: #521.
We now send aggregation commands along a cursor batch size for compatibility with MongoDB 3.6 that no longer supports aggregations without cursor. We consume the whole cursor before returning and converting results and omit the 16MB aggregation result limit. For MongoDB versions not supporting aggregation cursors we return results directly.
Original pull request: #521.
We now make sure that we convert empty sources to the corresponding target type. This prevents entity instantiation from failing due to incorrect argument types when invoking the constructor.
