wizard module was relying on implicit symbol linking for pages. since
i chnaged dlopens to be local this broke page loading. this local
dlopen change is all about not leaking symbols into the global table
which is good/right, but this stops the wixzard setup from working, so
move to explicitly exposing symbols to the modules in a struct.
this adds moldova (moldavian?) flag for layouts of keyboards and
refreshes some of the generic images for unknown, latin america, brail
and arabic "flag" images, and forces flag icons to be 2:1 aspect
ration with icon centered within that area to address T647
* disable all dummy wizard callbacks in pages
* shutdown callbacks in pages are now actually called
* pages are no longer shown repeatedly by xdg wait callback
* first page no longer accidentally the whole second page
* scaling initially set to 1.2 so the text is actually readable
* page states added so we have some idea where the hell the pages are at
