Add a combined dialog prompt for all weapon attack inputs

[kmoschcau]

Only prompt for missing information.
For example, when attack is executed from inventory, no need to prompt for skill. When a target is selected, no need to prompt for range.

Weapon attack prompts should be dialog boxes, not chat messages. The chat is only for the results.

This can be made even more generic, by passing an object with metadata to the prompt, having it generate a form dialog according to that and return the object with filled data.
