Make damage bonus part of weapon damage string

Original title: Extend weapons model to allow natural weapons without damage-bonus
Duplicate issue Sling Should have Half Damage Bonus

Some natural weapons should not include damage bonus in the damage they make. Figure out a good way to model that in the weapon item data.

Edit:

Implement the possibility to include db in the damage of a weapon, in the same way as damage is presented in the Weapons & Equipment book, for example 1d8+1+db. This also means that the previous "automatic" db must be removed so all weapons in a world must be migrated to get the correct addition to their damage (+db, +db/2 or no damage bonus).

Some melee weapons also needs 1/2 damage bonus in addition to no Damage bonus!

A rule anomaly is that some weapons have special rules at a Special Hit. Can be good to have it included .... thinking there might be a feature that shows a text window when hitting Special or crit .... have seen that there are for melee weapons

Should we introduce a special code db that can be used in the damage field. In weapons&equipment book the damage is specified in the form of 1d4+1+db or 1d6+1+½DB (more natural 1d6+1+db/2). This way you can decide the db per weapon.
Either the Roll code should be extended to fetch the db from the actor (is there a link?) or in the weapon chat code the db part could be replaced with the db, for example if db is 1d4, then 1d6+1+db/2 -> 1d6+1+1d4/2
