Changes

I made this template to replace the tag provided by the <nowiki><spoiler></nowiki> extension, because for some reason it seems to bypass some of the MediaWiki formatting. This version uses the same Javascript code, but doesn't rely on the backend php code extension for the spoiler tag, so <strike>the content of the spoiler is treated as standard MediaWiki formatting</strike>.

Also<span style="color:red">Actually, this still doesn't allow talbes inside the spoiler. Oh well, I guess we can have a little more freedom to style the button or make it look nice later (add a little icon for example)into an image and whatnot.</span>
