Offer to set safe configuration if reltool:start fails
Offer to set safe configuration if reltool:start fails

If a module is duplicated in the library directories visible to
reltool, and the configuration does not point out which file to use,
then reltool:start will fail. This commit adds a pop-up which asks if
it should continue with a "safe" configuration:

 [{incl_cond,exclude},
  {app,kernel,[{incl_cond,include}]},
  {app,stdlib,[{incl_cond,include}]},
  {app,sasl,[{incl_cond,include}]}]
