Update jquery.validity.core.js

Added support to enable/disable "infer" to display the title of the field.

A workaround may be to put title="&nbsp;" in the control, this should however decrease the number of code changes when you don't want to use inferring.
Merge branch 'patch-7' of https://github.com/markvantilburg/validity into markvantilburg-patch-7
Reverted to unix line endings
When useInfer is false, use the default field name
