(svn r17996) [0.7] -Backport from trunk:

Browse Source 
- Fix: [NewGRF] 'last_value' and 'reseed' are shared between procedure and main chain, 'scope' and 'count' are not (r17672)
- Change: [NewGRF] Apply default refitmasks only when the NewGRF did not set any of the three refittability properties (xor mask, positive classes, negative classes) (r17663)
