added an override for the civ files

- the civ controls currently don't have unique tags for the various
settings (skills, materials, caravans, etc.). these changes allow
file(s) to be specified that will be used instead of searching through
all raws for tags
- added support for new tileset/color 'DawnFortress'
- re-applied previous changes for the new manuals, and changes to
orcs/kobolds/warlocks
