Unifies grammar for morale types

[Ilysen]

Summary

Content "Fixed up some grammar with morale events"

Purpose of change

Inconsistent writing is always crummy, I think! A lot of these were capitalized inconsistently or had punctuation where they shouldn't.

Describe the solution

Audited all the entries in morale_types.json to follow standards that the rest of the game uses. There are some exceptions to grammar (for instance, traits that provide a fixed morale bonus/malus are still capitalized the same as the name of their respective traits, not including Mood Swings), but in general, they should all be grammaticized in the right places now.

Also renamed Diazepam Craving to Craving prescription sedatives, since DDA doesn't use trademark names for meds anymore.

Describe alternatives you've considered

• Some of these might actually be unused. I wasn't sure, though, so I just updated all of them.
• All of these could be capitalized in each word like a title instead of lowercased like a regular sentence, but I figured this would look strange. Anguished By Memories of Butchering a Human Corpse feels really awkward to read, at least to me, but Anguished by memories of butchering a human a human corpse doesn't!

Testing

Spawned in a bunch of stuff using debug to test various morale types. Murdered the poor starting NPC to make sure that that one worked correctly. I didn't test all of these since they're just string changes, but if requested, I'll totally make sure that all of them work.
