Subject: Remove 3rd party libs from our repository and define the dependencies
 in composer.json-dist. Also remove the ancient utf8 lib and replace it with
 'Patchwork UTF-8 for PHP'.

For direct git checkouts, copy composer.json-dist into composer.json and run
`php composer.phar install` to install the dependencies.

-Description:
-    Class provides functionality to convert single byte strings, such as CP1251
-    ti UTF-8 multibyte format and vice versa.
-    Class loads a concrete charset map, for example CP1251.
-    (Refer to ftp://ftp.unicode.org/Public/MAPPINGS/ for map files)
-    Directory containing MAP files is predefined as constant.
-    Each charset is also predefined as constant pointing to the MAP file.
----------------------------------------------------------------------------------
-Example usage:
-    Pass the desired charset in the class constructor:
-    $utfConverter = new utf8(CP1251); //defaults to CP1250.
-    or load the charset MAP using loadCharset method like this:
-    $utfConverter->loadCharset(CP1252);
-    Then call
-    $res = $utfConverter->strToUtf8($str);
-    or
-    $res = $utfConverter->utf8ToStr($utf);
-    to get the needed encoding.
----------------------------------------------------------------------------------
-Note:
-    Rewrite or Override the onError method if needed. It's the error handler used from everywhere and takes 2 parameters:
-    err_code and err_text. By default it just prints out a message about the error.
