Nexus Mods app adds new context menus, Stardew Valley FOMOD support, and work towards Bethesda games

I'm getting more excited about the open source cross-platform Nexus Mods app, especially as we're getting closer to Bethesda games support. Going to be really great when it's more ready since this has Native Linux / SteamOS support, finally a good proper fully featured mod manager for Linux integrated with the biggest modding site around.
