v1.6.9 - I heard her call my name

Lots of small tweaks in this update, as we're working on some major upcoming features, but thing worth calling out is a suggestion we've had a few times now: minion renaming! Any minion can now be renamed from the minion management screen, so feel free to name all your imps after your pets! I'm personally partial to celebrity name puns.

Additional changes:

• Gem rebalance - removed the bad attributes from the 3 basic single-stat gems
• Minion & item tweaks - potions and shields are more effective, increased the power of many minion abilities, mostly the healers
• New Kobold & Hobgoblin abilities - they now get stronger based on the number of Kobolds or Corrupted in your deck
• Expanded tutorials - the tutorial scroll in the early levels is now more interactive and highlights things on-screen
• Full help menu - the Help (?) tab in the book now has extensive game information and tips
