V0.5a update

Been hard at work patching the many bugs. Of those I have found I’ve only got three left to fix. Two minor ones about a number of syntax/code structure/typos on a couple of pages. And one major one that’s causing a page not to display any content at all except for the title and the back button.  The bug on that page itself is probably relatively minor - but there’s a LOT of content on that page to sift through.
