Better selection and cursor size.

For an older skin using the "includePaddingInMetrics" method from the blog, I had to use this to get previous behavior:

```
protected void drawSelection (Drawable selection, Batch batch, BitmapFont font, float x, float y) {
	float adjust = font.getDescent() / 2;
	textHeight += adjust;
	super.drawSelection(selection, batch, font, x, y + adjust);
	textHeight -= adjust;
}

protected void drawCursor (Drawable cursorPatch, Batch batch, BitmapFont font, float x, float y) {
	float adjust = font.getDescent() / 2;
	textHeight += adjust;
	super.drawCursor(cursorPatch, batch, font, x, y + adjust);
	textHeight -= adjust;
}
```
