Import courier-unicode-1.4 as mail/courier-unicode.

This library implements several algorithms related to the Unicode Standard:
 -  Look up uppercase, lowercase, and titlecase equivalents of a unicode
    character
 -  Implementation of grapheme and work breaking rules
 -  Implementation of line breaking rules
 -  Several ancillary functions, like looking up the unicode character
    that corresponds to some HTML 4.0 entity (such as "&", for \ 
example),
    and determining the normal width or a double-width status of a unicode
    character. Also, an adaptation of the iconv(3) API for this unicode
    library
 -  Look up the Unicode script property
 -  Look up the category property
This library also implements C++ bindings for these algorithms.
