(svn r4501) -Fix: (FS#129) When, in a train that head multiple engines in front, the _first_ of those engines is sold, all the orders are copied to the second engine (to ensure "seamless" operation). However, during this operation, it was forgotten to update the prev_shared and next_shared pointers of the new head engine AND the next_shared and prev_shared of the share partners.

(svn r4500) - NewGRF: When running a callback with no vehicle, use the purchase list 'cargo' type first, and then fallback to the default if needed.

(svn r4498) - Use an item's name instead of value when parsing configuration lists.

(svn r4497) - NewGRF minor fixes: (Rubidium)
- Remove a define in favour of using the lengthof() an array.
- Fix typos in language names enum.
- Add Brazilian ISO code.

(svn r4496) - NewGRF: switch custom engine names from storing a char* to using the new StringID based text system. Vehicle name
translations now work.

(svn r4495) - NewGRF: Implement conversion from old language IDs (bitmask) to new language IDs (value)

(svn r4494) - NewGRF: Clean up and reset custom texts

(svn r4493) Newgrf : Action 04. Beginning of implementation.
Some TODOs left, but the core is there.
Thanks to Peter1138 for code, advice and patience
And to Patchman for letting us define a lot of langids :)

(svn r4491) - Codechange: handle IGT_LIST types just as the other types with a proper name and value setting (for example for newgrf parameters).

(svn r4490) - Feature: The integer-list parser now accepts a space character as an item seperator next to the comma.
