MidgardSchema ( "oh my god , they killed MgdSchema" )

It's going to be brief.

MgdSchema is no longer supported. Initial Midgard MgdSchema C structure is succesfully replaced  with new object oriented MidgardSchema and MidgardSchemaClass.

A few benefits:

• Language bindings for schema initialization will be easy to write
• MgdObject and MgdObjectClass share the same data with MidgardSchema
• MidgardSchema data are global for midgard-core while private and invisible for midgard "extensions" like midgard-php.
• Memory management follows GObjects' rules
• Initialized Midgard Reflection is much easier to write and extend.
• Application's schema can be "extended" from xml standalone files ( private ones ) or directly from directories.
