New option to make "AS" aliases aligned vertically

[javaDeveloperKid]

Hi, it's often more readable when selected column aliases are aligned vertically.
Instead of this:

SELECT
  foo as one
  foofoo as two
  foofoofoo as three

we can have this:

SELECT
  foo           as one
  foofoo      as two
  foofoofoo as three

Configuration option for that would be nice.
