center-v1.3.0

The following changes have been made since v1.2.0:

Completion changes:
  - zsh completions now properly support long options.
  - _arguments is now called with “-s -S” since apparantly it doesn’t
    actually support being called with “-sS”.

Makefile changes:
  - _POSIX_C_SOURCE is no longer defined.

center changes:
  - Long options are officially supported.  This will allow usage in
    scripts to be more readable.
  - PROG_ARGS and the program option string are now constant char
    pointers, not macros.
