check existence of uncompressed or compressed info files for doc viewer
* parser.cc (set_info_path): return type changed to bool, checking existence
of info file uncompressed and with all known compressed file extensions,
returns false if no file was found and true after parsing the found file;
* parser.h: return type of set_info_path changed to bool
* webinfo.cc (ctor): do not check existence of info file since this is done
via set_info_path;
(set_info_path): return type changed to bool, load Top-node if
parser::set_info_path returns true and return the related return value
* webinfo.h: return type of set_info_path changed to bool
