unicode-clickatell.patch

This patch allows passing the 'unicode' flag to the Clicktell HTTP API. If set,
it will be passed verbatim to Clickatell as an HTTP request parameter. It is
expected that it's set to either 0 or 1. If set to 1, the message text must be
a hexstring of the UCS-2 representation of the string, as with the following
Ruby snippet:

ucs2 = Iconv.conv('UCS-2', 'UTF-8', text)
hexstring = ucs2.unpack("H*")
