INI Parser new features

From PlcWiki

*   $Log: iniparser.cpp,v $
*   Revision 1.11  2010/03/29 14:18:23  dsmid
*   Added dot notation:
*   with .....:
*   means chop four segments from current prefix (four levels down), the first dot means 'current prefix'.
*
*   Revision 1.10  2010/03/25 16:03:01  dsmid
*   Mapping directives can be now added directly to primary config:
*   #map key.translate.* = value
*   Such directive affects only subsequent content.
*
*   New mapping directive .rename= allows to rename key prefixes:
*   #map old.key.prefix.rename = new.key.prefix
*   Applied on all keys starting with "old.key.prefix"
*
*   New construct 'with key.prefix:' allows to write more readable configs:
*   with my.key.prefix:
*    .subkey1 = value1
*    .subkey2 = value2
*
*   Equivalent of:
*   my.key.prefix.subkey1 = value1
*   my.key.prefix.subkey2 = value2
*
*   Indentation is optional, isn't required.
*
*   Revision 1.9  2010/03/24 15:15:10  dsmid
*   Enabled relative include paths
*
*   Revision 1.8  2010/03/24 13:03:44  dsmid

*   Then any non-hidden files in directory <original file path>.d/ are read in alphabetical order.
