Client::SetMana corrections

[cybernine186]

I have found some flaws in the Client::SetMana causing items like Manastone and Cannibalize to not work properly. Also Client::DoManaRegen() does a unnecessary call of the SendManaUpdatePacket(); twice.

Here is a diff of the latest version of PEQ. Please let me know how it works for you.
