Bypass to conditions (and CriztianiX "columns type" pull requrest too)

I had pulled in the commits from @CriztianiX re "columns type" -- it's a good pull request waiting on you...

but if you only want to pull in the specific bypass commit, it's really basic: https://github.com/AudiologyHoldings/CakePHP-Elastic-Search-DataSource/commit/889e7deaf8eda4ad55047715be96117b0abc4522
