Evening patch: UI improvements, little bit of balance — Heat Death Steam update #1829020

Patch notes: - I improvements and fixes have been added, based on what I saw during Wanderbot's twitch stream earlier today. More will likely come. - The 3rd boss had an attack which would grow significantly stronger as the combat progressed. It has been nerfed from +3 per turn to +2 per turn, but starts at 5*5 damage instead of 4*5. - It is no longer possible to turn off "Additional Tooltips". This setting is excessive and confusing, so I'm removing it for now. - "Instant animations" will now be just really fast, instead of all instant. I decided to make this change because of how jarring it looks when everything happens at the same time. I might make this a dropdown selection in the future, with the option "normal / fast / instant", because some people might like to speedrun.
