Memorial upgrades

Done so far:
- Memorial file displays type of ammo and amount of ammo remaining/clip size of carried weapons.
- Added mod and world options info. Displayed world name.
- Changed starting memorial message.
- Cash display
- Kill list not shown when empty.
- Added martial art styles
- Traits only show up when there are traits.
- Starting traits listed
- Added starting stats, these are only set on character creation.
- Starting values (not skills yet) are listed in the memorial file.

Other stuff:
Also wanted to make it more clear what your starting chosen options were. (started with traits xyz, stats etc. If we also allow uploading of these files that could provide some interesting data). Calculate cash on hand + cash on debit cards.

And try to fix any other bugs. Like death damage not calculated in the damage taken value.

Any requests for changes to the memorial file?
Edit: https://github.com/CleverRaven/Cataclysm-DDA/pull/2860 this seems to be broken currently. Edit guess not. Could not reproduce it.

That will only give you the mods ident, not the displayed name. You need to look that up in `mod_manager::mod_map`, which is private, so you need to add a function to that class that does the lookup.
