make contructor of ThMenu a regular function, somehow it can't be bound (=>)
add handler to lookup vin by last 5 chars
don't complain about program logo if id don't have one
add special dict type for vin move all from dictionaries to local-dict

so now dictionaries only register different kinds of dictionaries and
can be used as access point to them

to register new dictionary it should have dict field in it's module
returned object, and be added to dictionaries as dependency

local-dict now have all that stuff from dictionaries
plus interface for new typeahead
