[Open Assets] Bento Box v3

- Added a new map: Standoff Saloon
- Updated thumbnails for all maps (The TV border was jank)
- Added staff ghosts to each race
- Did the dishes

Blue Sphrings conflicted with the worms in Bowler Pack. Should be fixed now

Added a brand new race map, dubbed Aquatic Coast. also split the race and battle maps into separate packs to make updating easier (and in case people don't want the battle maps)

(also the third time uploading this update, as the first time there was a map issue, and the second time the filenames were wrong)

Chrome Gadget has been properly finished, with a brand new shortcut. Assembly Assault was also resized and modified for minimal bonk and maximum flow. Full changes in the changelog. Flying Frigate received no updates, because it doesn't need updates right now :)
