Supported ANSI C's asctime() format in Time::parseHTTPDate().
Added Time::parseAsctime(). Changed order of application of parse
functions. I could not remember why parseRFC850() was tried first.

Added --conditional-get option. Download file only when the local
file is older than remote file. This function only works with
HTTP(S) downloads only. It does not work if file size is specified
in Metalink. It also ignores Content-Disposition header. If a
control file exists, this option will be ignored. This function
uses If-Modified-Since header to get only newer file
conditionally. When getting modification time of local file, it
uses user supplied filename(see --out option) or filename part in
URI if --out is not specified.
