[FEATURE] Multiple lighting items

[ZotyDev]

Currently OIF can only handle a single lighting item, it would be nice to be able to have multiple light sources on the same token, it SHOULD be easy to make. The plan is to use combine the options, using the higher values, and maintain the lighting animation of the last used item.
It could be possible to create lighting sources and attach them to the character, thus making it possible to have true multiple lights, this approach should be tested to see if its doable, in case of a positive result it must be implemented.
