Don't limit render distance in preview mode

Closes #716

doesn't seem to work for me? i expect genesis plaza to stay loaded when i leave, and nothing else to load.

if you go to an empty parcel it keeps that scene loaded, if you enter a populated parcel it changes the preview to that parcel

[robtfm]

hm ... i think it should just stick with the initial preview scene

[hukasu]

how would you change the scene being previewed?

[robtfm]

by restarting with the new location.

preview mode isn't really meant for walking around the world, it's meant for inspecting a scene while working on it.

[hukasu]

would it make sense disabling /goto and /world if in preview?

[robtfm]

yes, but i don't think it's necessary

[robtfm]

is the grass behaviour expected?

[robtfm]

i note it works well if i use a cmd line including the position, but if i don't then i end up stuck on the loading screen. does it help if we leave the preview parcel None if not specified, and overwrite it once we know the target parcel?
