----------
1) wysiwyg editor:
  * Now the site theme is applied in the wysiwyg editor
  * enhancement of handling of <pre>:
  Now ensure that a block of preformatted text are encapsulated in one pre tag. 
  The problem was in IE. he split a pre block into two blocks of pre when breaking 
  a line.
  * IE and href property of <a>:
  When creating an anchor tag (a link). IE prefix a relative link with the current 
  domain and app name. Now it is corrected by scanning the document when 
  saving and correct the bad hrefs.
