IconicButtons.init calls ClickableWidget.getMessage on the partially initialized ClickableWidget passed in from MixinPressableWidget. This causes crashes in some mods, which haven't fully initialized their widgets yet. An example is World Host, where I haven't loaded the messages for the button yet, causing getMessage to NPE.

A potential solution would be to simply remove the IconicButtons.init call in MixinPressableWidget, and let renderIcons take care of it (which it will without any other changes, since it calls init if the text has changed, which it will have changed from null by the time it's called).

Fixing this will fix Gaming32/world-host#76.
