  Make appendDecimal use the last char of the buffer
  
  ImmutableStringBuilder(1) means 1 char usable payload and \0.
  
  This this should fit appendDecimal(1) but did not. Fix the off by one
  error calling snprintf.
  
  Also:
   * removes const & from uint32_t argument
   * removes const & from operator<<, to stay consistent
   * Removes a redundant static_cast
   * Implements operator<< const char* with potentially better
     operator<<(const ImmutableString&) (may get compile time strlen)
  
  Fixed: angleproject:8567
