Compiled: here

Testing:

Please tick the box as you complete each test segment.

• [x] Base functionality test
  • Delete your config file
  • Start game
  • Ensure that you can summon unlimited minions
  • Quit game
• [x] Limit increment test
  • Edit config file to impose a limit on skeletons and draugr (different limit for each)
  • Edit the incrementer for each minion type (or leave it as default of 10)
  • Start game and check that you are being permitted to get new minions each time you get another X levels of Necromancy skill
  • Quit game
• [x] Limit no increment test
  • Edit config file to have incrementers set to 0
  • Ensure that the limit can't be passed and that no extra minions are given as necromancy level increases
• [x] Mixture test
  • To be exceedingly thorough, test incrementer with skeletons works well without an incrementer on the draugr, and vice versa

There's a divide by zero error when either MinionLimitIncrementsEveryXLevels is set to 0.

Aw man, could've sworn I accounted for that possibility... haha. Thanks

Oh wait, you did. It was just because you checked one and used the other, which means it will be resolved with https://github.com/jpw1991/chebs-necromancy/pull/117#discussion_r1124113434
