improve: better player group flags management

[dudantas]

Description

This allows us to add or remove flags on specific players, for example, so that a certain player is not visible by a monster, or cannot drop loot at a certain time (for example, in a specific quest). Instead of the flags being determined globally, they can be set differently for each player, depending on our wishes.

Behaviour

Actual

Flags are defined globally, in groups.xml, and cannot be modified in a specific player.

Expected

We can now modify the flag in just one player, if we want.

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested

Try to add this for example in login.lua:

	local haveSkill = "no have"
	if player:getName() == "Druid Sample" then
		player:setGroupFlag(PlayerFlag_NotGainSkill)
	end
	if player:hasFlag(PlayerFlag_NotGainSkill) then
		haveSkill = "have"
	end
	Spdlog.info("player name: ".. player:getName().." flag: ".. haveSkill.."")

Change the name "Druid Sample" to the name of the player you want... When he logs in, he will have the flag of not advancing skill when attacking a monster. The same can be done to remove the flag.
