(svn r19044) -Codechange: don't load the 'new game' NewGRFs when you're certain the savegame wouldn't have been saved with them, i.e. don't load the 'new game' NewGRFs for TTO savegames.

* NewGRFs were introduced between 0.3,4 and 0.3.5, which both
* shared savegame version 4. Anything before that 'obviously'
* does not have any NewGRFs. Between the introduction and
* savegame version 41 (just before 0.5) the NewGRF settings
* were not stored in the savegame and they were loaded by
* using the settings from the main menu.
* So, to recap:
* - savegame version < 4: do not load any NewGRFs.
* - savegame version >= 41: load NewGRFs from savegame, which is
* already done at this stage by
* overwriting the main menu settings.
* - other savegame versions: use main menu settings.
*
* This means that users *can* crash savegame version 4..40
* savegames if they set incompatible NewGRFs in the main menu,
* but can't crash anymore for savegame version < 4 savegames.
*
* Note: this is done here because AfterLoadGame is also called
* for TTO/TTD/TTDP savegames which have their own NewGRF logic.
