Prevent null pointer dereference on early error
If a fatal error occurs before CRT_init has been called, CRT_done
dereferences NULL in CRT_colors.
Simply check if CRT_crashSettings is not NULL, which is eventually
set when CRT_init has been called.
If it is not set, then do not try to disable ncurses.
Proof of Concept (on Linux):
$ ./configure --with-proc=/var/empty
$ make
$ ./htop
