Journal modifier

Journals are common, so let's have a dedicated journal modifier instead of requiring the artist to hook up Python nodes for this.

I think there are a lot of common things we can try to provide streamlined interfaces for (I've already done this with the "default" settings on some of the modifiers).

Linking books would also be a great candidate for simplification, IMO.

How do you envision this mod? Attached to a book mesh, which it plugs into the Activator Attribute, a field for the region, and then fields for the rest of the configurable options on the xJournalBookGUIPopup? I think that's all it would need.

How should we handle the Localization text and path selection? Blender's text editor is still primitive, so I'm not sure that it's ideal to handle it all internally. Better to let authors use plLocalizationEditor (or hand-write them if desired). On the other hand, it would be smooth to have better integration.

@Hoikas: With the incoming #128, will we want to convert this to use Blender text note blocks as well, so that we can properly package or export the loc files too (as discussed in #41)?

[Hoikas]

That's probably a good idea
