1.0 :
	Based on 'kio_http'/
	Use a URI-Scheme 'k2ch'.
	Use a User-Agent 'Monazilla/1.0 (K2ch/1.0)'.(configured in kio_k2chrc)
1.1 :
	'K2ch::filterURL()' converts '/test/read.cgi' to '*.dat'.
	Mime-Type for '*.dat' is forced to "text/html".(in convenience, due to no viewer plugins for "text/x-2ch-dat")
	It will be forced to "text/x-2ch-dat".(Now commented out) 

1.2 :   Override 'HTTPProtocol::stat()' and now we can check the 'Last-Modified' value changes with K2ch::stat() by KIO::UDS_MODIFICATION_TIME.
	!!Notice!! KIO::UDS_MODIFICATION_TIME doesn't have a time value but a checksum of 'Last-Modified:' string.
