Added support code to allow CSET chunks to be read from clipboard IFF FTXT and

converted as necessary.  Added option to write UTF-8 direct to clipboard, setting CSET
appropriately.  Copying and pasting to/from webpages that are not in local charset and
to/from other applications that set CSET when not using local charset, should now work
correctly if clipboard_write_utf8 is set in the options.  If not set, NetSurf will
still convert from the charset specified in the clipboard when pasting, but will
convert text to local charset and not write a CSET chunk for copy operations.
