rename race_ to _race, to follow the style guide.
refactoring: moving unitname to unit.c.
also removing static-string some cruft from config.c.
load inifile in main, it is only used by the server.
this should fix the broken CI build.
units without a name will use their race as a default name.
eliminate unused variables, fix CI build.
added a function that sets a monster's name to NULL if it is the name of its race.
deprecate old rc_name function (renamed to rc_name_s) because it used a static return string.
space savings: update data files, remove names from NPC units where their name is their race.
Merge pull request #60 from badgerman/master

NPC units that use their race as the name (Hirntöter, Seeschalnge) can use NULL as their name.
