- Removed defaults from `cross_tab`. It caused an out-of-heap space error when it attempted to build a 205k x 205k table. Now has a hard limit of 10,000 columns - we can increase this once we have more concrete test data.

- Adjusted the dropdowns on `Aggregate_Column` for `columns` and `order_by` to be dropdowns as nested Vector editors are not supported.

- Altered `Aggregate_Column` so `new_name` now `new_name:Text=""` and not taking `Nothing` anymore. Makes it appear correctly in IDE.
