Render to new renderslot

[Weisl]

`import bpy
from bpy.app.handlers import persistent

@Persistent
def PostRender(self):
bpy.data.images['Render Result'].render_slots.active_index += 1
bpy.data.images['Render Result'].render_slots.active_index %= 7

bpy.app.handlers.render_complete.append(PostRender)`

Include this into the addon. Figure out the UI
