Discordia intent for DMs only

Making Discordia bots receive only DM related events and no text channel events or any other useless event. Useful for DM only Lua Discord bots on Discordia.

Edit Shard.lua in Discordia and add these two lines:

		guild_subscriptions = false,
		intents = 2^12+2^13,

Like this:

	return self:_send(IDENTIFY, {
		token = client._token,
		properties = {
			['$os'] = jit.os,
			['$browser'] = 'Discordia',
			['$device'] = 'Discordia',
			['$referrer'] = '',
			['$referring_domain'] = '',
		},
		compress = options.compress,
		guild_subscriptions = false,
		intents = 2^12+2^13,
		large_threshold = options.largeThreshold,
		shard = {self._id, client._total_shard_count},
		presence = next(client._presence) and client._presence,
	}, true)
