v4.1.2

Patches

• Speed-up most common .all usage: #3

• If parent is specified but it's undefined/null, don't ignore it: bd578b9

  Given this:

   const parent = select('nonexistent')
   const children = select.all('.children', parent)

  select.all would look in the whole document, instead of just returning "none found in nonexistent"

  This releases fixes this error and matches jQuery's behavior
