Forms API documentation not up to date

[sdm]

2 remarks about the forms API documentation on the following page:
​http://docs.outerthought.org/kauri-docs-0_4/217-kauri/363-kauri/478-kauri.html

• There is no documentation for get/setValue()
• The documentation for the 'noValidation' parameter is incorrect: it says "optionally triggering validation" but it should be "optionally skipping validation"

I've added the suggestions.
