Drop-mod

Welp, that's a big change. Well, not in terms of "how to use the library", rather how the library itself does stuff, and how its code looks. All thanks to [pylint](https://pylint.org/)!
*(Oh and by the way, 1.5.1 has a pylint score of **0.32/10** (!), whereas 1.6 has 9.14/10.)*
So far the least optimized thing is drop's GUI frontend. Because, let's be real, it's half-baked and rushed. Buuut, I tried all that I could.

Change-list
- Added very basic module descriptions
- Capped the line limit to 100 instead of 120 *so code lines will be less long than they were*
- Module variables now follow the `UPPER_CASE` naming style
- Optimized imports *(no more wildcards)*
- ~~Accidentally~~ fixed the search function a bit
- Did some minor but numerous changes to the GUI a bit *(too many for me to list them, 'cause this update is about code optimization dangit.)*
- Drop exceptions now raise *from* the original Python exception
- Er, `__version__` is now at `1.6`

this time i hopefully won't release broken code
- Fixed lyric functions
- `edit_guild_todo()` is now a thing
- Config commands now work!..... *god dammit.*

why did I suddenly gain motivation?

- `migrate_user()`, to migrate every warns, mutes and temp bans from one user to another
- **Guild/bot commands are here!** drop-mod can now handle config files for you.

not even 24 hours and I already updated.
- Fixed `get_steam_app_info()`
- Added `format_names()` (from `['john', 'jane', 'weird name']` to `john, jane and weird name`)

hello. it's been a while. *ahem*
- 1.4 now, I swear time flies.
- Added a ProtonDB summary function
- Added a game searcher using some super fancy HTML/regex haxx... I'm not good at talking skid language.
- Added a basic function to get info about a Steam app using its API

- Removed a few problematic owofy registers
- \_\_version\_\_ can actually count
