delegates: don't use starts-with search to fetch cylinder/weight data

In the wightsystem-type and cylinder-type delegates, when entering
data, when entering known weight- or cylinder-types, some ui fields
(notably weight, size and working-pressure) are automatically filled
out. The search was using the default flags provided by Qt: starts-with
and case-insensitive.

This had a few strange effects, when entering a string that is the
beginning of a known string (e.g. "AL6" when "AL63" already exists):

1) The wrong data was used if the new string didn't exist.
2) For cylinders it was impossible to create new cylinder types whose
   name is the starting string of a different type.
3) For weights, the new type was not added to the list of known types.
   This, however, is no problem, because it will be added by the undo
   command anyway. A future commit will address that redundancy.

Therefore use only the case-insensitive flag (which has to be performed
by passing the MatchFixedString flag - very weird).
