Linux Download Poorly Named

The linux download is poorly named, as the scripts are not for linux, but ubuntu.

For example, to get this running on arch linux;

```
sudo pacman -S enet luarocks love rsync # networking, luarocks manager, love 0.8.0 and sync software you use
sudo luarocks install enet # Lua bindings
```

If you're going to distribute this game under the pretense it is for linux (e.g. any linux) just tell them to install the following;

rsync (for update.sh)
enet (for luarocks)
love 0.8.0

Then tell them if their repo does not have the lua enet version, that they will need to install it via luarocks.

As an aside; cool game! It has a lot of potential!
