Add const to char * in BWRequest typedef

Fixes many gcc --Wwrite-string warnings of the form:

Bitmap.c: In function ‘BWTPaste’:
Bitmap.c:1913:7: warning: passing argument 2 of ‘BWEngageRequest’ discards qualifiers from pointer target type
Bitmap.h:190:16: note: expected ‘BWRequest’ but argument is of type ‘const char *’
