Mediawiki 1.17 upgrade
Upgraded EduTechWiki to Mediawiki 1.17 and also upgraded most extensions. As usual, the upgrade was easy and flawless.
In addition, I decided to explore Semantic MediaWiki and in particular its Semantic Forms extension. Right now, I don't know what I shall do with them nor do I yet understand any technical details. Keep tuned, I may use these extensions for representing some types of information (e.g. about educational design systems). I also see great potential for implementing learning scenarios, e.g. we could use Mediawikis instead of other portalware like Drupal to implement forms-based student writing scenarios.
I also added a skin for handhelds (mobile devices). This may break older browsers, but I don't hope so.
