Title: Fix issue where it runs anyway if no non-nop mappings given and adds warning for nop mappings

..._L=Escape;Control_R' it would add a mapping from that key to NULL list of to keys. Now it will simply skip over the mapping with no to and print a WARNING that the statement has no effect to stderr. Also, where before if only nop mappings were provided the program would still run/fork into the background; it now will only run if at least one mapping with an effect is provided.
