Sort lists with localeCompare

The difference in case sensitivity is the most obvious change with
servers like soju that support CASEMAPPING ascii and
rfc1459. Currently the list:
  'Alpha', 'aardvark', 'Charlie', 'comma'
currently sorts to:
  'Alpha', 'Charlie', 'aardvark', 'comma'
with this change it will instead become:
  'aardvark', 'Alpha', 'Charlie', 'comma'

If something like RFC 7613 gets broader support then there are a few
more differences for a list like:
  'éclair', 'ecstatic, 'aardvark', 'zed', 'Gamma'
currently sorts to:
  'Gamma', 'aardvark', 'ecstatic', 'zed', 'éclair'
with this patch would instead sort to:
  'aardvark', 'éclair', 'ecstatic', 'Gamma', 'zed'

The above examples were run with a locale unspecified which fell back
to my browser/host default of 'en'.
