Improved the pagination buttons of the explorer GUI.

Browse Source 
* NEW: updated the pagination button to more clean ones, and through an overrideable method, to allow a more in-depth personalization if needed. The way used to implement this may be improved, but it's not very important.
* NEW: added a version of `ActionGui.updateAction` with only the action and an ItemStack as argument.
