This should avoid any format inconsistencies, like missing newlines and the like.
Although a basic save and load works, there may still be some issues with the format.
This probably renders older saved games incompatible.
The format is mostly the same, but there are a few small changes
in the name of making the format more uniform.
- Changed cPlayer::equip to a bitset
- Use a static constant instead of a loop to initialized player starting spells
- Only save spell points if the player has any (current if different from max)
- Symbolic forms for trait enum (and save symbolic forms also for skills)
- When loading a player, clear data which is not always present in the file
- Also add an init test for cPlayer
