William Wilgus af573708ed extend filetype_get_plugin() search for viewer by fileext
I noticed the way filetree switch was modified
for the lua (and then) opx and  open plugin viewers
since builtin files are assumed to be handled in the filetree switch
what if instead filetype_get_plugin() could search the available viewers

this could probably be extended further with selectable defaults
