Small store bug fixed

[exxos]

I had a spam filter setup a few weeks ago to filter out any bitcoin addresses as I was tired of getting those spam emails. However we have just found that occasionally a order number would look like a bitcoin address and be blocked by the system :roll:

I think the only consequence was when orders are marked as done, possibly people would not get the order update emails. I would think a lot of people probably don't get them anyway because of the general email problems. Certainly no orders have been lost on the system or anything major like that. We think this has only happened to 2 orders but it is difficult to really tell.

But anyway, that problem is hopefully fixed now. All order numbers now should start with "EX" and that will break the bitcoin preg_match filter.
