Basic placeholder implementation of item upgrades.

What works: Should be nothing, this is the groundwork for someone more experienced to work with.

What doesn't work: All of it, at least maybe you can click the button and get no response, but it's just a placeholder for what we need to do.

What needs done: Well, since we don't handle how upgrades work in the core, we need to implement this, by this I am saying we need to make sure we have the formula down for how the upgrades work, as well as, we need to have the upgrades be purchased with valor points, rather than gold.

This is a pretty basic and generic implementation, but hopefully it can get someone started on the complete implementation of it. If nobody else wants to, I will.. but I didn't have time before work today ^^

P.S. It may not be the prettiest and best work in the world, nor the most difficult. Just want to contribute something, seems a bit dead around here sometimes.

Cheers!
