Patch 1.23

There were a couple hotfixes over the past couple of days that I'm summarizing below in addition to a few smaller tweaks that I just patched. Thanks for the continued feedback and reviews everyone!
[h2]Patch notes (v1.23)[/h2]

• In the Boom Town challenge, you can now only be damaged once per TNT crate (even if you're caught in multiple of its explosions at the same time).
  
• Added option to turn off (un-)fast-forwarding via mouse aim button (speedrunners rejoice).
  
• Added options to specify the mouse-wheel aim adjust sensitivity.
  
• Fixed Boss Rush challenge starting with one more shot than it should.
  
• Fixed last TNT crate in a turn sometimes not exploding due to a race condition.
