* Adjust page change animations to slide the page closed and then
open again.
* Add Railcraft to the standard set of mods
* Change every controller which uses an `ImageLoader` to only accept
it from a parent controller (with the router creating the one
shared instance).
* Fix several places where controllers need to refresh when the mod
pack changes
* Fix a few places which should be using the `ImageLoader` but were
not.
* Remove a number of animations which caused performance issues (esp.
animating individual items in item group views).
* Fix a bug where changing the current version of a mod didn't cause
the current crafting plan to be re-evaluated
* Simplify the name finder to allow regular expressions instead of
the current algorithm
