Subject: [PATCH] execute `op_block` nodes

The commit 8bbcc2a473812ebac2fc6d30a808352fbab4441b added an `op_block` node, for blocks of code inside curly braces.
A case was added to the `compile` function, but no corresponding case was added to the `execute` function, so blocks of code just aren't executed any more.

So code like this:

```
if(true) {
    point(0,0);
}
```

would produce nothing, instead of a point at the origin.

I think that just executing the single child node is all that needs to happen.
