Large changes to embed docs, GridFS files, and indexes. Additionally, the following outstanding issues were addressed: * Discourage use of Timestamp and Key types (closes #974) * Remove example of embedding a Document-mapped class (closes #907) * Clarify Field name option specifies the database field name (closes #686)
As mentioned in the changelog, __clone() methods will no longer be invoked. This is a BC break for code that might have relied upon that behavior.
