Feature: Support floating points for more precise XP buffs

[bhavinamin]

Describe your feature request or suggestion in detail

Currently this module only supports integers for the xp multipliers. Putting in a floating point number such as 1.25 for a 25% XP increase will return invalid in the server console and will revert to the conf defaults. By supporting floating point, we can fine-tune XP rates more precisely.

I fixed this in my own local install with the code block below and tested it successfully, was just too lazy to fork and pull request.

Describe a possible solution to your feature or suggestion in detail

Basically we do the math in float then cast back to int.

void OnPlayerGiveXP(Player* player, uint32& amount, Unit* /*victim*/, uint8 /*xpSource*/) override
    {
        float rate = 1.00;
        if (sConfigMgr->GetOption<bool>("Dynamic.XP.Rate", true))
        {
            if (player->GetLevel() <= 9)
                rate = sConfigMgr->GetOption<float>("Dynamic.XP.Rate.1-9", 1.00);
            else if (player->GetLevel() <= 19)
                rate = sConfigMgr->GetOption<float>("Dynamic.XP.Rate.10-19", 1.00);
            else if (player->GetLevel() <= 29)
                rate = sConfigMgr->GetOption<float>("Dynamic.XP.Rate.20-29", 1.00);
            else if (player->GetLevel() <= 39)
                rate = sConfigMgr->GetOption<float>("Dynamic.XP.Rate.30-39", 1.00);
            else if (player->GetLevel() <= 49)
                rate = sConfigMgr->GetOption<float>("Dynamic.XP.Rate.40-49", 1.00);
            else if (player->GetLevel() <= 59)
                rate = sConfigMgr->GetOption<float>("Dynamic.XP.Rate.50-59", 1.00);
            else if (player->GetLevel() <= 69)
                rate = sConfigMgr->GetOption<float>("Dynamic.XP.Rate.60-69", 1.00);
            else if (player->GetLevel() <= 79)
                rate = sConfigMgr->GetOption<float>("Dynamic.XP.Rate.70-79", 1.00);
        }

        amount = uint32(std::round(amount * rate));
    }

Hey man, where and what file should I edit to paste those lines?

Thanks in advance!
