* Added versioned namespace accordding to configure.c
* Fixed missing namespace for SerializableMapDualKey interface
* GObject Introspection fixes

* Simplified implementing GObjects having Serializable Gee
  collections by adding SerializableContainer interface
  and implementing se/deserialization in SerializableObjectModel
* Serializable Gee Collections now return default node_name
  from its elements
* Fixed bugs on elements' content and unknown properties on
  complex tree with sub-containers
* Fixed bug on unknown Text elements
* Fixes, new ones and improves to Unit Test

* Serializable deseralize/serialize unknown properties disable by
  default. Override get_enable_unknown_serializable_property

* Requires GLib 2.32, Vala 0.20, Gee 0.10.5
* Unit Test pass
* Node Unit Test improvements
* Added some Element Unit Tests

* NodeList requires Gee.Collection interface implementation
* NodeList removed unused API
* Removed GListNodeList implementation
* Replaced GListNodeList with Gee.ArrayList
* ChildNodeList is now a read only Gee.AbstractCollection
* Test ported to new API

* Serializable: added serialize_use_xml_node_value () for classes
  requiring to save its content to GXml.Element contents
* Ported all implementations to new Serializable API
* Found a bug in deseralize/serialize/deserealize Gee Containers,
  so added tests cases to reproduce it. Not Fixed Yet.

Keeps changes on Serializable and Serialization from serializable
branch.

* Renamed SerializableMapId to SerializableMapKey
* Renamed SerializableMapDualId to SerializableMapDualKey
* Renamed functions to get Keys for SerializableMapKey and
  SerializableMapDualKey to avoid conflics with implementator's
  use of id() and primary/secundary_id () functions/properties.

* SerializableObjectModel fixed warnning message and just show
  when DEBUG is defined

* Now properties with cannonical names, chacaracters '-' are removed to
  find nodes names to serialize.
* SerializableGeeArrayList and  DualKeyMap now throws GLib.Error on
  non Serializable objects types
* SerializableGeeArrayList, DualKeyMap and TreeMap just deserialize GXml.Element
* Added new test case for convined Gee Collections

* SerializableTreeMap now rize an error on unsupported type on deserialize
* Added a test case (and example) on how to implement a class with a
  SerializableTreeMap property

* Renamed serializable_node_name to just node_name ()
* Renamed and convert as function serializable_property_user_nick
  to property_use_nick
* Updated SerializableJson, SerializableObjectModel and Unit tests

* Fixed use of camelcase representation of a enum property in a
  GXml.Attr
* Fixed: no serialize enumeration with invalid value
* Fixed: no deseralize enumeration with invalid GXml.Attr value
* Changed SerializableEnumError to EnumerationError and INVALID_NAME to
  to INVALID_TEXT

* Added tests cases for Enumeration class

* Now serializable_node_name is a method to be overrided
* SerializableObjectModel declares it as virtual to allow
  overrides in derived classes
* SerializableObjectModel print message for problems with
  serializable_node_name value
* Updated tests cases

* Added Node copy method, Element and Attr implementations too.
* Fixed unknown attributes de/serialize () for SerializableObjectModel
* All unknown properties are serialized back again to original file, to
  avoid data lost on de/serialize operation
* Fixed issue with Element content text, using Text node representation
* Added unit test for unknown properties de/serialize
* Added unit test to avoid serialize properties set to null

* Added test case for unknown property saved to
  Serializable.unknown_serializable_property

* Added test case for custome node name
* Added test case when overriding deserialize
* Added documentation to Serializable.ignored_serializable_properties
