- Removed NadekoCommand and Aliases attribute from all commands

- All commands must be marked as partial
- Added [Cmd] Attribute to all commands
- Cmd Attribute comes from the source generator which adds [NadekoCommand] and [Aliases] Attribute to each command
- Should be updated in the future probably to be more performant and maybe add extra data to the commands
- Started reorganizing modules and submodules
