New feature: food system requires mercs to eat and drink in order to survive

- food and water levels are lowered every hour, eat food to survive
- not doing so leads to various penalties and ultimately death
- added food items for that purpose. Food can degrade over time. Rotten food poisons.
- Mercs automatically consume food if hungry/thirsty and food is in their inventories
- for more info, see http://www.bears-pit.com/board/ubbthreads.php/topics/307396/Re_Mercs_need_food_and_water_t.html#Post307396
- this feature requires new STI files from the GameDir trunk.

- added a bunch of filler variable to the soldier type, so hopefully savegame compatibility can be maintained easier in the future.

WARNING: This will break savegame compatibility
