Support StructBlocks defined directly in the model

[mikemonteith]

A struct block doesn't necessarily always have it's own class definition.

From Wagtail's docs (http://docs.wagtail.io/en/v2.0/topics/streamfield.html#structblock):

('person', blocks.StructBlock([
    ('first_name', blocks.CharBlock()),
    ('surname', blocks.CharBlock()),
    ('photo', ImageChooserBlock(required=False)),
    ('biography', blocks.RichTextBlock()),
], icon='user'))

This is an alternate to defining a class:

class PersonBlock(blocks.StructBlock):
    first_name = blocks.CharBlock()
    surname = blocks.CharBlock()
    photo = ImageChooserBlock(required=False)
    biography = blocks.RichTextBlock()

    class Meta:
        icon = 'user'

At the moment, wagtail-factories only supports the class-based definition:

class MyTestPageFactory(wagtail_factories.PageFactory):

    body = wagtail_factories.StreamFieldFactory({
        'carousel': MyCarouselFactory
    })

    class Meta:
        model = models.MyTestPage

MyCarouselFactory has to be a subclass of wagtail_factories.StructBlockFactory, which depends on there being a class definition of the struct block.

Hopefully I will get time to look into this more. Has anyone come across this before, or have any ideas about how to solve it?
