redmine_highlightjs do not display HTML / XML / CSS code in repositories

[alxRlja]

All code HTML / XML / CSS in the repositories, is translated, instead of being displayed "as is" so , for example if I have an HTML file in the repository, when I see the page, the page elements are translated and it tries to display the elements inside (like tables, IFRAMES, sections, DIVS, XML CSS , etc) instead of the code. Unfortunately this is a big deal, so for now I'll uninstall until further notices for updates. Thank you for the plug-in, I'll keep track of it. I think its a great idea.
