Look into using Bukkit's builtin Bed Location Fetcher

I recently found [getBedSpawnLocation](https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#getBedSpawnLocation()) in the Bukkit API, and after some testing it seems useful for bedmode b as is. With some modifications, it could be used instead of the plugin's beds database.

Possibly submit a PR to @SpigotMC with code for returning a bed location even if it isn't null?
