Fixed reCAPTCHA text - signup form

[Dillon Lawrence]

The reCAPTCHA field states 'Enter both words from the box above:', whereas reCAPTCHA now usually shows just one or shows numbers.

It would probably be more appropriate if the field read 'Enter the numbers or words from the box above:'

ReCAPTCHA is still pretty consistently 2 words for me but it does make sense to make the text be a bit more generic. Thanks!
