LANG-1404 BooleanUtils.toBoolean(Integer) method added

[Enigo]

Right now to convert an Integer to boolean there is either a null check needed:

final Integer value = 1;
if (value != null) {
    if(BooleanUtils.toBoolean(value)) {
        // some code
      }
}

or two methods call:

final Integer value = 1;
final Boolean b = BooleanUtils.toBooleanObject(value);
if (BooleanUtils.toBoolean(b)) {
    // some code
}

Some code-sugar is added with the help of method that accepts Integer and returns boolean:

final Integer value = 1;
if (BooleanUtils.toBoolean(value)) {
      // some code
}
