StaffMod Module Improvements - Add enabledByDefault

[ItsNature]

Overview

Description:
Adds an enabledByDefault parameter to the Staff Mod Module's enable methods so servers can choose whether granting a staff mod also activates it on the player's client.

Changes:

• New methods on StaffModModule:
  • StaffModModule#enableStaffMods(Recipients, List<StaffMod>, boolean enabledByDefault)
  • StaffModModule#enableAllStaffMods(Recipients, boolean enabledByDefault)
• The existing no-flag overloads delegate with enabledByDefault set as false.

Code Example:

  public void enableStaffModsExample(Player viewer) {
      if (!viewer.hasPermission("apollo.staff")) {
          return;
      }

      Optional<ApolloPlayer> apolloPlayerOpt = Apollo.getPlayerManager().getPlayer(viewer.getUniqueId());
      apolloPlayerOpt.ifPresent(apolloPlayer -> this.staffModModule.enableStaffMods(apolloPlayer, Collections.singletonList(StaffMod.XRAY), true));
  }
