Return empty string instead of 'undefined'

What if obj[name] === 0?

The only cases I can see where you'd probably not want to print out the toString() of a falsey obj[name] is:

• if obj doesn't have the name key or
• the value of obj[name] is undefined
• the value of obj[name] is null

Printing 'false' and '0' seems reasonable to me.
Perhaps something like this would be better:

var value = obj[name];
if (typeof value === "undefined" || value === null) return '';
return value;

hmm yeah -.5 from me haha, typically you'd want to do data-show etc and toggle an entire element, the text content of one blank may be a little hard to track down if we're converting to an empty string. Also since .value() is public IMO it should be the canonical value and if we were to convert to empty string it should be done in the data-text binding and have a value == null check like @timoxley mentioned to handle undefined/null

going to close this one for now, we do need a way to opt-out of setting the text at all for some cases as well, as a sort of default mechanism, but it without opting in it would be annoying and not really all that obvious
