API: Column selector - add support for visible indexes counting from the right

Browse Source 
- The ability to use negative numbers as a column selector for the
  column data index was added recently, but that didn't include the
  ability to work with negative numbers with the :visible pesudo
  selector. This commit adds that ability so you can do:
  `table.column("-1:visible")` to always get the right most visible
  column
