Convert options to getopts standandard

[awiebe]

There might be no way to do it without breaking backwards compatibility, but specifying options to rdfind is really strange as currently implemented.

Long options should really be specified as
rdfind --makehardlinks <path>
instead of
rdfind -makehardlinks true <path>

To be consistent with other command line tool invocations.

Hi,
I agree the syntax is awkvard, I think I just mimicked some other command I used at the time. It has crossed my mind to change the options to the more well recognized syntax. However I made a decision to keep it, in order not to risk confusion and backwards compatibility. I believe that was the right choice.
