Files created on alpha/beta won't work at vanilla

Description

When trying to open a file created at earlier versions, BlenderDMX breaks in many different ways.

This happens mostly due to the new structure that finds the GDTF "root geometry" and flags it as a "Root" object. On earlier versions, we would assume an object called "Body" as the fixture root. This should be seen especially on BlenderDMX GDTFs, which were created under this assumption.

Workaround

There's no safe way to make this backwards compatible, so we're not solving it. However, the following script should fix most cases:

• On Blender, go to the Scripting tab.
• Click the + New button.
• Paste the script and run it.

#
# [BlenderDMX v1]
# 
# Update Fixtures from earlier versions.
# Please note this might not work for some fixtures.
#

import bpy
dmx = bpy.context.scene.dmx

for fixture in dmx.fixtures:
    for obj in fixture.objects:
        if (obj.name == 'Body'):
            obj.name = 'Root'

    # This line refers to the issue #26, and should not be necessary on later versions
    fixture.emitter_materials.clear()

    fixture.build(
        fixture.name,
        fixture.profile,
        fixture.mode,
        fixture.universe,
        fixture.address,
        fixture.gel_color,
        fixture.display_beams
    )

I'm keeping the Issue open for feedback on the patch. If necessary, I'll make updates to it.

Seems like no more issues on this. I will close this now.
