TextArea improvements

[howudodat]

Please consider or add the following improvements to TextArea:

1. unset word wrap inherited from dui-field. In my opinion TextArea should wordwrap and scroll by default. The following css allows it to word wrap

textarea.dui-field-input {
	white-space: unset;
}

Alternatively a css class or helper function could be created: TextArea.wordwrap() { getInputElement().setCssProperty("white-space", "unset");

2. Allow sizing of TextArea. Currently to size a TextArea, it needs to be sized by rows, or the following line needs commented out (I see no reason to even have setHeight("auto") so please consider removing it)

  private void adjustHeight() {
    // getInputElement().style().setHeight("auto");
    int scrollHeight = getInputElement().element().scrollHeight;
    if (scrollHeight < 30) {
      scrollHeight = 28;
    }
    if (autoSize) {
      getInputElement().style().setHeight(scrollHeight + "px");
    }
  }

3. Allow sizing through TextArea.setSize()...It seems a bit unusual that to size the TextArea I need to call TextArea.getInputElement.setSize(). I understand why, but it's not intuitive

4. Alternatively allow the TextArea to consume it's parent's height (dui_h_full). This too requires dui_h_full to be set on every layer and requires height:auto to be removed, a helper function here would be nice.

taBillingNotes.fixedSize();
taBillingNotes.addCss(dui_w_full, dui_h_full);
taBillingNotes.getBodyElement().addCss(dui_h_full);
taBillingNotes.getWrapperElement().addCss(dui_h_full);
taBillingNotes.getInputElement().addCss(dui_h_full);
