An implementation of (s)printf() for LPC, with quite a few
extensions (note that as no floating point exists, some parameters
have slightly different meaning or restrictions to "standard"
(s)printf.)  Implemented by Lynscar (Sean A Reith).

This version supports the following as modifiers:
 " "   pad positive integers with a space.
 "+"   pad positive integers with a plus sign.
 "-"   left adjusted within field size.
       NB: std (s)printf() defaults to right justification, which is
           unnatural in the context of a mainly string based language
           but has been retained for "compatability" ;)
 "|"   centered within field size.
 "="   column mode if strings are greater than field size.  this is only
       meaningful with strings, all other types ignore
       this.  columns are auto-magically word wrapped.
 "#"   table mode, print a list of '\n' separated 'words' in a
       table within the field size.  only meaningful with strings.
  n    specifies the field size, a '*' specifies to use the corresponding
       arg as the field size.  if n is prepended with a zero, then is padded
       zeros, else it is padded with spaces (or specified pad string).
 "."n  presision of n, simple strings truncate after this (if presision is
       greater than field size, then field size = presision), tables use
       presision to specify the number of columns (if presision not specified
       then tables calculate a best fit), all other types ignore this.
 ":"n  n specifies the fs _and_ the presision, if n is prepended by a zero
       then it is padded with zeros instead of spaces.
 "@"   the argument is an array.  the corresponding format_info (minus the
       "@") is applyed to each element of the array.
 "'X'" The char(s) between the single-quotes are used to pad to field
       size (defaults to space) (if both a zero (in front of field
       size) and a pad string are specified, the one specified second
       overrules).  NOTE:  to include "'" in the pad string, you must
       use "\\'" (as the backslash has to be escaped past the
       interpreter), similarly, to include "\" requires "\\\\".
The following are the possible type specifiers.
 "%"   in which case no arguments are interpreted, and a "%" is inserted, and
       all modifiers are ignored.
 "O"   the argument is an LPC datatype.
 "s"   the argument is a string.
 "d"   the integer arg is printed in decimal.
 "i"   as d.
 "c"   the integer arg is to be printed as a character.
 "o"   the integer arg is printed in octal.
 "x"   the integer arg is printed in hex.
 "X"   the integer arg is printed in hex (in capitals).
