0.5

This is a major pfgrep release, now including:

• pfzip, a tool to make archives out of source libraries/files/physical file members/streamfiles. It converts them to standard UTF-8 text inside of the archive, and preserves text descriptions as file comments
• Other minor tools like pfcat (print PF member/EBCDIC streamfile) and pfstat (print PF info as tab-separated values).
• Man pages are included, you can refer to i.e. man pfgrep for command help.
• Support for the -m option to limit matched reeturned.
• Support for the -A option to print lines after the lines matched.
• Improve iconv handling (reset shift state, use iconv directly)
• Modularize pfgrep code to handle streamfiles and record files the same way.
