Adding 'IniConfigFile' mapper for 'ini'-style config files.
Adding 'IniConfigFile' mapper for 'ini'-style config files.

This class simplifies the parsing of common 'ini'-style configuration files and
provides several useful utilities, such as get(section) and get_key(section,
key).  The intent is to avoid repeating the same parsing patterns throughout.

At the moment it treats lines that start with either ';' or '#' as comments,
strips leading and trailing spaces from lines, and throws away any
configuration lines that come before the first section header.
