ToDo/RedoNavigationBar

The current navigation bar is outdated, and rather useless. We should update it, so that it's more useful.

Goals

 * Removed outdated or incorrect links
 * Remove stuff related to non-used social media
 * Removed partner sites, which aren't really useful anyways
 * Change "Updates" section to list the recent updates, with manual links on particular features/items from that update?
 * Change the "Minecraft PE" menu to something more useful... Maybe to list the various game actions like mining, adventuring, fishing, or listing structures? Maybe also here list specific blocks/items which are common to look for? (Not just use the general categories which give random links to whatever pages?)

Tasks

 * Find all outdated links
 * Reconsider the overall structure
 * Reconsider the social media and partner site idea
 * Start implementing stuff... tbd :-)
