Ship Preview Expanded

Expands the Ship Previewer at empire creation to see much more of what your shipset is including Megastructures! Sadly not Achievement Compatible. Currently only has the normal bio ship classes + their growth stages (which are not present in vanilla). Due to the way paradox implemented bio ships, it is very tedious to add the megas and other models for viewing with the bio ship sets. Maybe I will add them if i get around to it in the future. Should work with any shipset mods. Does not have compatability for mods that add new ship classes. Please note that not all ships/entities will be displayed when using other mods. Other mods might have different model implementations or not have models at all. As such, don't report issue with other shipsets not having models. Let me know if there are any changes I should make. Probably wont ever need an update, so don't comment about it. :)
