Furnace should support disabling strict loading of addons based on API version

   /**
    * Set this {@link Furnace} instance to use strict {@link Version} checking when loading addons. If enabled, addons
    * with an {@link Furnace} API version higher than the current {@link Furnace} runtime version will not be loaded. If
    * disabled, addons will be loaded regardless of the {@link Furnace} runtime version on which they depend. (Defaults
    * to <code>true</code>.)
