[SVN:r3230] Updated BuffMerchant.cs

[Leodagan]

I changed Buff procedure from static to object one...

I did not liked the queues being instancied weirdly (static param in class, but new object given to a static procedure...) and I needed "this" to cast spell handler...

I also made the buff procedures "Pet" compatible, and added a const to actually enable or disable it...

I also made a const to spell duration, and set it to max... on my server buff don't wear out and stays flashy, so it's better to have them forever (easy to change if you like)

Thank you ! Can you please commit with the current (limited) duration ?

Commited to SVN 3230 with 2 hours buff duration (and pets buff enabled...)
