Lassi Kortela b7db5bb755 Rename string.split into string-split

Lassi Kortela 78b663d41d Add help and colored banner 
- (help ...) is a macro that quotes everything to be user-friendly
- (help* ...) is the equivalent procedure
- When the user types just `help` or `exit`, the REPL shows a hint
  that they are probably looking for `(help)` or `(exit)`.

Lassi Kortela 9d4bf19367 Fix regression in ios_printf implementation 
There was some problem with the way the varargs are handled. We had to
need to make (at least one) copy of them with va_copy(). The code is
brittle and I don't understand it, so just rip it all out and replace
with a fixed-size static buffer. It's a hack but we'll soon get rid of
printf completely so this will get us through the day until then.
