Add action_name_prefix and use_fake_user

[cuddlyogre]

Add an option to specify an action name prefix and to mark whether the sent action should have a fake user. There is a companion addition to cc_blender_tools. The rationale is that it makes it easier to organize and preserve poses and motions sent to Blender.

Ok, I'll take it.

There may be problems with Retargeting if later Rigifying as I use the first part of the name to identify the source rig... however I am going to move away from putting the identifiers in the name, as this is too easy to break, and put them in custom properties instead, so this won't be a problem much longer.

I've cleaned up the action name prefix code. Sequences weren't fetching the name prefix, and my naming logic for the replace_action_motion was almost non-existent. I have it renaming all the actions according to the character/rig name and using the prefix as appropriate. It also now doesn't remove any pre-existing actions, only the unused ones from the motion import.

I've also got the initial character import (Send Avatar / Go-B button) to also use the action name prefix.

All in all it's a good feature.

Fantastic! This feature saved me probably a couple hours of work yesterday and I'm glad it can help other people, too. The code for this plugin is very clean and intuitive. It was a treat to work with.

Is there a way to get the name of the pose/motion when you apply it to the character? If so, having that be the default name or prefix for poses and motions would be incredibly helpful.

I've looked through https://wiki.reallusion.com/IC_Python_API:RL_Python_Modules#Animation but I'm not finding anything.

Clips do have names but it is not exposed in the API.
