Updated Local Cluster Creation page, fixed images on content pages that are image heavy

Game Information

I re-worked some of the text for the Local Cluster Creation page and added diagrams for the "Link systems" example section. I also added a short description of how we allowed players to modify system attributes after systems were linked up with FTL routes.

New Features

Reworked the pages that were image heavy (like the sapient species page) so that links from the table of contents were not nerfed by the Markdown rendering engine.
