Complete the Crafting Table view/controller

* Add output box to the crafting table view
* Add remaining crafting patterns to all MC 1.7.10 recipes
* Add all crafting patterns to Buildcraft 6.2.6
* Disable mods which don't have patterns yet
* Add the Url constants for computing urls from templates
* Add the `findItemDisplay` to ModPack (along with tests) and remove
  all replace all uses of `getPathSlugs` with it
