readded old dreamer splits, added some new stuff

[cerpintext]

from updates.xml:

• Leave Sly hut transition split with lantern bought
• Added splits with the old dreamer timings for 'save-quit -> load-in early control' timesave
• Filler Abyss (Lighthouse lit + Abyss gate opened) split points because I wanted them for practice points :)
• Resorted some splits so they should be together with their pairings (ie. enter boss + defeated boss by each other) in non-alphabetical order
• Renamed 'ending' to 'Credits Roll (Event)'. Useful for All Achievements
