More config for CreateCommand, add various methods

Adds multiple configurations to the command builder, and adds methods
to various structs.

Context::get_current_user is a shortcut to retrieve the current user
from the cache.

Message::get_member retrieves the member object of the message, if sent
in a guild. Message::is_private checks if the message was sent in a
Group or PrivateChannel.

User::member retrieves the user's member object in a guild by Id;

Adds 6 configurations to the command builder:

- dm_only: whether the command can only be used in direct messages;
- guild_only: whether the command can only be used in guilds;
- help_available: whether the command should be displayed in the help
  list;
- max_args: specify the maximum number of arguments a command must be
  given;
- min_args: specify the minimum number of arguments a command must be
  given;
- required_permissions: the permissions a member must have to be able
  to use the command;
