Add Layouts For Pages

- Added different layouts for each page so the navigation panel dropdown
will stay "dropped" down when you are viewing a page. E.g. Viewing a mod
the "Mod Library" navigation bar will stay dropped down.
- There could be a better way of doing this but I'm no laravel expert.
- If you want a better method of doing this or me to change/edit
something just say and I will tweak away :)
