Merge branch 'feature/345-debounced-validate-fix' into feature/vue-2.5.9

* feature/345-debounced-validate-fix:
  remove uniqueId import
  fixes #345 - declare debouncedValidateFunc and set it when debouncedValidate() is called... vue 2.2.0 prevents you from attaching methods/properties to components that have not been declared
