Expanded Sentries/Progression

Here's a list to show what items for this mod you can get based on game progression, a checklist of sorts. This does not include sequence breaking, like using the Reaver Shark to get Hellstone prior to defeating any bosses. The Wrangler, Engineering Toolkit, and potions continue to be useful beyond the stages listed here. This shows the earliest they can be gained. A few vanilla items, changed to Defender class specific, are included too.
