Support natively a few straightforward transformations

[Seddryck]

The idea is to support a few straightforward transformations such as

• blank-to-empty: if the current content of the cell is blank (zero or many spaces) replace the content (empty)
• blank-to-null: if the current content of the cell is blank (zero or many spaces) replace the content (null)
• empty-to-null: if the current content of the cell is empty (length=0) replace the content (null)
• null-to-empty: if the current content of the cell is null replace the content (empty)
• null-to-value: if the current content of the cell is null replace the content (value)
• any-to-any: replace the content of the cell by (any)
• value-to-value: if the cell's value is not null will replace the content by (value)

For this we'll need to support a new language native
