Misc Entrances Issues

[mattman107]

I'm working through entrance randomizer in #19 and I am finding misc issues involving our vanilla entrance graph that need to be addressed, but I am really deep in changes to the repo and I don't want to stash or commit. Just feeling lazy so I am going to list the issues I find here. This is mostly so I remember to clean them up later.

1. Something was up with the Gerudo Fortress and Thieves Hideout entrances around the break room hallway
2. zoras_river.py has events for Hyrule_Field day/night
