Pops up a modal warning dialog, blocks until user dismisses

app - ceed.Application, we get QSettings from there

parentWidget - parent Qt widget of the spawned dialog

title - window title of the spawned dialog

message - message text, plain text

token - this is used to remember whether user dismissed to never show again

token is generated automatically from title and message if None is passed.

For messages containing diagnostic info this may not be appropriate. The

info inside will change, thus changing the token and user will see the

same warning again. Passing a proper descriptive token is advised.
