Add prop updateImmediately to FormsyText

[codeaholicguy]

I added prop updateImmediately to FormsyText in case someone want to get status valid or invalid of textbox immediately when user fill in.

Usage

<FormsyText
  name='name'
  updateImmediately
/>

Updating on every change is slow for text inputs. Need to add some debouncing here.

@krizka good idea

[krizka]

Please, look at my gist in comments to #97

@krizka Nice, I added debounce for solving performance issue with calling setValue continuously

[krizka]

We can not call debounce every time we want to change, but have to get a function from debounce and call it many times. That is why I making setValidate method only once on component mount.

that why I created this.changeValue

if (this.props.updateImmediately) {
  if (this.changeValue) {
    this.changeValue(event.currentTarget.value);
  } else {
    this.changeValue = debounce(this.setValue, 200);
    this.changeValue(event.currentTarget.value);
  }
}

Oh, sorry, now I got it. Nice job)
To be more clear and dry, maybe.

if (!this.changeValue)
  this.changeValue = debounce(this.setValue, 200);

this.changeValue(event.currentTarget.value);
