bugfixes

At long last, the official Zrep version 2.0, that is bash based, for greater portability.

At this point, bash(4.4?) seems to have absorbed almost every single feature I was using, that was previously specific to ksh.
Almost no tweaks were neccessary other than time format, and print -> echo.

Since true ksh is practically impossible to get these days... the future needs be bash based.

I hope everyone, new and old, will continue to get good use out of Zrep

This may be the last official ksh version release of zrep.
I wanted to make an official release bundling everything, before I move to v2 and bash.
A nice amount of bugfixes.

ChangeLog:

    added check for /etc/default/zrep
    added ZREP_CREATE_FLAGS and ZREP_INIT_REMOTE_PROPERTIES
    fixed definition of ZREP_SEND_FLAGS
    added ZREP_DATEFORMAT
    added ZREP_R fixes
    added zrep status -m
    more resume tweaks
    fixes for zrep refresh and allowed zrep -R refresh
    safeguard check for zrep takeover
    fixed an expire bug

Mostly just bugfixes, including a critical resume-support bug.
