Fixing a bug with unwanted line wrapping of text and html e-mails: WordUtils.wrap treats the incoming string as one line, regardless of line breaks within the string.

in fact the problem with ie was related to the css class definitions in the dump tag. we will adapt this change but we have to rewrite int a little bit, we never use the split method in cases like this because it is a regex method, for that we use the Lucee ListUtil and we also have centralized System property calls. In addition we will also adapt it for Lucee 5. so i keep this pull open but we will adapt it asap.
