Inventory Viewer V1.0 - Ready to go!

So this is the first version of my inventory viewer.

The buttons are disabled for time being - this is because they are not done, but it looks empty without them. So I just did some extra css work to disable them.

I know of a few non-optimal issues, for example - If you have wool in your inventory, rather than showing the correct colour. It shows black no matter what (because for some reason what's the default)

Support for Ender and Survival inventories - With armour (We didn't have armour before :D!)
Also support for ALL inventories within the multi-world inventories structure. I have only added buttons for the two main inventories, but you can access other worlds by changing the URL appropriately.

Will be doing more work on this now - but wanted to PR this. It's all working etc, and is a upgrade from our current one.
