src/Main/options.cxx: replay url: improved location of local file.

Browse source 
We now put local file inside directory specified in /sim/replay/tape-directory,
and also use 'url-' prefix on leafname.

E.g. with
    --prop:/sim/replay/tape-directory=.../fgtapes and
    --load-tape=http://foo.com/harrier-gr3-continuous.fgtape

- the local file is:
 .../fgtapes/url_foo.com_harrier-gr3-continuous.fgtape
