J3/Bootstrap use hasTootip rather than hasTip

I doubt that this will fix my disappearing fields problem which is
apparently a result of a conflict between mootools more and bootstraps
use of jquery and which is fixed by using hasTooltip rather than hasTip
... but these are the uses of hasTip in things that are obviously J3 /
bootstrap.
