Remove the cscope -q flag. I always forget it, and no need to rebuild

all the time.
Also, I've recently switched to excflags.

src/Makefile

 all: tags cscope.out
 
 cscope.out: cscope.files
-	cscope -b -q
+	cscope -b
 
 tags: cscope.files
-	xargs ctags -d < cscope.files
+	exctags -VL cscope.files
 
 cscope.files::
 	find build conio sbbs3 smblib uifc xpdev -name '*.c' -o -name '*.cpp' -o -name '*.h' > cscope.files
