Better Statistics Screen

Fixed Issue #15, but not in the way one may initially expect. Thank you DeathdealerYT for reporting the issue. Issue #11 is semi-related.

The core root of these issues comes down to how the game handles statistics internally vs what is shown on screen.

• For user convenience, both the vanilla statistics screen and the better statistics would display both item and block statistics into one big merged interface featuring both.
• Fundamentally speaking, the game does not work like that internally. Blocks are clearly NOT items, and vice-versa. Same applies to statistics about them. Visually they may seem interchangeable, but they are NOT.

Therefore, merging these into one interface (like how the vanilla statistics screen does) leads to janky code that tries to treat both as if they are the same thing when they clearly are not. In other words, the programming code gets messy.

To resolve this issue - I have decided to step away from presenting both as one (like how the vanilla game does), instead presenting them as they truly are in the game's code - by splitting them into two separate views; "Items" and "Blocks". This provides a more accurate view into what statistics data really looks like, but it also means that you will now no longer see block-related statistics among items and vice-versa. This also automatically resolves Issue #11 and Issue #15 on the spot.

[Edit] Forgot to mention

Added /give @s to right-click context menus. Convenience feature for quickly giving yourself an item/block you might want. Requires access to /give for this option to show up.
