Decor Updates

- Fixed decorators using the same RNG when picking from a pool of blocks as it used to place it. This caused it to only use pool entries above the placement chance threshold. (E.g. a flower pool with a 0.15 chance to place will only use the first 0.15 of the pool of flowers since the RNG is the same)
- Removed `zoom`, `verticalZoom` and `varianceZoom` properties from decorators. Zooms can be done inside the individual styles instead.
- WIP Tab Completion (Create command only rn)

Dev notes:
It's very important from now on that in decorators, the X and Z remain switched when getting noise so that the result of the noise is not exactly the same as the noise that choose if the decor should be placed or not
