constify strings in resource name registry

LookupResourceName already returned a const char *, so just needed
to change the variable we're storing the list in to be a const char **
and then add const to the name argument to RegisterResourceName
(which just stores name in the array) and CreateNewResourceType
(which just passes name to RegisterResourceName).

Clears a bunch of gcc warnings of the form:
registry.c:319:5: warning: passing argument 2 of 'RegisterResourceName' discards qualifiers from pointer target type
registry.c:200:1: note: expected 'char *' but argument is of type 'const char *'

and from all the extensions:
damageext.c: In function 'DamageExtensionInit':
damageext.c:490:5: warning: passing argument 2 of 'CreateNewResourceType' discards qualifiers from pointer target type
../include/resource.h:159:26: note: expected 'char *' but argument is of type 'const char *'
