Edited vocab prefIds
Edited vocab prefIds

The prefIds for vocabulary questions weren't exactly descriptive. True, this wasn't exactly a problematic issue, but given the fact that I have some interesting expansion ideas for this feature, specifically the user-made vocabulary categories, and the possibility of people submitting their own vocabulary questions through pull requests, I thought it best to make the prefIds descriptive. That way, if I decide to make any major changes, it won't cause any sudden migration issues. After all, 'vocabulary_set_animals' will always refer to animals, but 'vocabulary_set_2' could refer to anything. I don't want the user to have selected animals, but then the app updates and 'vocabulary_set_2' now refers to food. And if I decide later on to make it descriptive, the user would lose all their selected vocab preferences, which is equally not on. So I thought I should do it now instead, before the vocab feature's first release.
