sw html import: fix handling of CDATA
In case the HTML contained markup like <![CDATA[...]]>, we simply
ignored it during import, even if e.g. the ODT import handles that
correctly.
The reason for this is that the svtools/ HTMLParser had code to parse
<!-- ... ---> style comments, but not for CDATA.
Fix the problem by introducing a new HtmlTokenId::CDATA, producing a
matching token content in HTMLParser::GetNextToken_(), and finally map
it to normal text on the Writer side.
Note that HtmlTokenId doesn't allow non-on-off tokens past ONOFF_START,
neither allows inserting a single token before ONOFF_START (it breaks
getOnToken()), so for now just add a second, dummy token to avoid
breakage.
