Render character model in first-person

[philpax]

When you enter first-person mode in FFXIV, your character model and that of your mount/anything else you're attached to are hidden. We should either find a way to show this, or hijack the third-person camera to render first-person.

I am leaning towards the latter as the first-person mode seems compromised in several ways (not being able to go first-person while sitting, etc).
