Enable Pasting of Text with embedded Links
With this Change pasting of plain text with embedded links
into Visual Editor will change in behaviour:
First, http and https links will no more be surrounded with
nowiki tags, but will be displayed as external links.
Secondly, every linebreak will cause a paragraph, so new lines and
double lines will work.
- inserting "this is http://www.example.com" will always make a paragraph;
- inserting multilines without any links will not be transformed;
- inserting not plain texts, but copy and paste from browser or msoffice will
be transformed by this change
