Subject: [PATCH] Added syntax highlighted code to clipboard as HTML when
copying
The generated HTML is not the prettiest HTML in the universe, but it
does the job. When copying code from Qt Creator to Microsoft Office or
OpenOffice.org, the syntax highlighting is now preserved. The code also
pastes as preformatted text.
