Layout section updated!

New on the website

Eastern Lane track plan made with Railmodeller Pro.

- The layout section has now been updated to suit for current plans, and now include new, more visual and detailed track plan screenshots, as I've begun to use Railmodeller Pro instead of Scarm.
- The "Overview" and "Modules" pages have been slightly altered and some text has been moved from one to the other for more coherency.
- Yet again, some corrections with spelling etc.
