Fixes + User Management Commands + Basic Sudoers System

[OcelotWalrus]

Summary

This PR adds some fixes:

• fixed some of the ecosystem.json file permissions and ownerships
• fixed the self.is_dir() function, which had some weird bug
• fix the prompt displaying the working directory in lowercases
• make so that when you're root, the $ becomes a #
• update the su command so that you also specify the group of the target
• also update the su command so that it checks if the target user at the target group actually exists
• also update the su command to include a --h argument that returns a help page
• make the self.filesystem var self.__filesystem

This PR also adds some new systems:

• add basic work of a sudoers file
• add a new check when loading /bin/, to skip a module if it contains a 'with open(' statement

This PR adds new commands and new os/script functions:

• the useradd command
• the userdel command
• the passwd command
• new os functions:
  • self.__pathos_bus_is_root() # return a boolean that tells if the user is authenticated as root
  • self.__pathos_bus_entry_exists() # check if an entry at registry.json exists
  • self.__pathos_bus_add_entry() # add a new entry to the registry.json
  • self.__pathos_bus_change_passwd() # change the password of a registry.json entry
  • self.__pathos_bus_remove_entry() # remove an entry to the registry.json
  • self.get_working_entry() # return the current user and group
  • self.add_user_entry() # script method to check if the user can add an entry to registry.json
  • self.remove_user_entry() # script method to check if the user can remove an entry to registry.json
  • self.change_password() # script method to check if the user can change the password an entry at registry.json

Check commit 3b4c030, I've added the useradd command.

@Monarchz3ro , I've a request: should I add this line of code, so there isn't pycache folders generating anymore? It's kinda weird and annoying that pycache stuff get generated in the root folder.

import sys

sys.dont_write_bytecode = True

[Monarchz3ro]

I'd rather not do that, because the cache is generated for a reason and speeds up the system, so I'd rather make the mockup simply ignore those files instead of not write them at all

[OcelotWalrus]

I've added the passwd and userdel command! I've tested them in every case, but feel free to test them yourself!

The PR is ready for review @Monarchz3ro !

Apologies, I've been busy with a few other aspects of the game (such as story and graphics), but I'll look at your PR

Mismatch: passwd.py has the help text for userdel

No worries.

Mismatch: passwd.py has the help text for userdel

I'll change that soon.
