[web2py] Propose to add case-independ like

[KMax]

Hello
  Postgres has ILIKE where clawse, but it postgres specific extention.
  Is there way to add .ilike to gluon of web2py DAL ?
  Or is there the way to add .ilike to dal at model initialisation.

  I know that .lower could be used to workaround case sensity, but I
have cyrillic chars and .lower() works on them only
with .decode('utf-8').lower().encode('utf-8') and more over, does not
work in dal-query at all.

  So, please advise.
