bugfix [#20639] BF25_SVN_25888 and below - OBJ and 3DS import fails

blender supports type changing for textures in a way that python doesnt.
add a new general function.

Example usage:
 tex = bpy.data.textures.new("Foo")
 tex.type = 'IMAGE'
 tex = tex.recast_type()

Macro to give the number of users accounting for fake user.
 ID_REAL_USERS(id)
Use this so you can remove a datablock if it has a fake users as well as apply transformations to it in the 3D view.

Move api function bpy.data.add_texture() --> bpy.data.textures.new()/remove()
