Add some missing and misspelled CSS2 properties and values
Add some missing and misspelled CSS2 properties and values

Currently the property 'speak-numeral' is misspelled. The patch
fixes the spelling of the keyword.
The property 'font' is missing the values 'caption', 'icon',
'menu', 'message-box', 'small-caption', 'status-bar'. The
property 'white-space' is missing the values 'pre-line' and
'pre-wrap'. The patch adds the missing keywords.
