v1.6

• Ability to put a Javadoc on enum values. To do that, instead of putting a String in the value, put an object of the form {"ENUM_VALUE_NAME": "Javadoc for this enum value."}
• Breaking change: renamed sqliteHelperClassName to sqliteOpenHelperClassName
• Breaking change: added mandatory databaseVersion field
