Improved the options.awk script; added an "everything off" option.
Revised contrib/pngminim to use the "everything off" option in pngusr.dfa.

version 1.5.0beta23 [April 29, 2010]
Corrected PNG_REMOVED macro to take five arguments.
The macro was documented with two arguments (name,ordinal), however
the symbol checking .dfn files assumed five arguments. The five
argument form seems more useful so it is changed to that.
Corrected PNG_UNKNOWN_CHUNKS_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED
