[TYPO3-RTE] Beware of CSS bug in Safari

[Stanislas Rolland]

CSS class names are case-sensitive. However, as of Safari 3.1 (525.13), 
the stylesheet API returns only lowercase text. Therefore, if css class 
names with uppercase letters are used, they may not appear in the block 
style and text style drop-down lists of htmlArea RTE because the check 
against lists of allowed classes fails. If you intend to use htmlArea 
RTE in Safari, you should make sure to use only lowercase letters in 
your CSS class names.
