📦 switching to dpy 2.0, new help command, fixes

[Kile]

This pr does not add a lot but fixes numerous bugs, cleans up messy code and starts using discord.py 2.0 using it's functionalities

This PR adds:

• A generic paginator in paginator.py using buttons
• A new help command, making it more dynamic and hopefully increasing user friendliness
• More error handler messages

This PR changes:

• rename functions.py -> checks.py
• .gitignore now includes **/env which prevents a virtual environment to be committed
• There have been changes in the README file appropriate to point 2
• web-scraping.py has now fully switched to asyncronous requests
• k!profile now includes the discord certified moderator badge as well as the nitro badge (if possible)
• All owner restricted commands now use the @commands.is_owner() decorator instead of an if statement inside of the command
• The prefix command has been moved from prefix.py (which is now deleted) to moderation.py
• All breaking changes from dpy 1.7 -> 2.0 have been changed
• The not used commands in __init__.py have been commented out

This PR fixes:

• A very ugly message if the id passed to k!profile was invalid
• No response when a certain error occured on all pxlapi commands
• An issue where the path to font.ttf had to be changed based on the machine it was run on
• An issue where you were unable to use certain commands in dms with Killua
• An issue with k!uwufy where it would add a line with just a -

All these changes and features have been tested

How commands have been changed for the help command:

- @commands.command()
+ @commands.command(extras={"category": Category.FUN}, usage="img <query>")
async def img(self, ctx, *, query:str):
-   #h Search for any image you want
-   #u img <query>
+   """Search for any image you want"""
    ...

TLDR; Killua switched to d.py 2.0 and uses prettier menus, plus is cleaner internally. It has a more appealing help command and had some bugs fixed.
