ArgvReceived() no longer calls Probe() directly, but builds a BMessage

Browse Source 
for RefsReceived().
Probe() now accepts a BEntry instead of an entry_ref, and all entries, too;
unacceptable nodes should be sorted out before.
RefsReceived() now sorts out BDirectories and will open one alert for
all directories, no longer one for each.
Added temporary hidden feature: pressing shift when opening a file will
make it possible to open symlinks and directories (to be able to access
their attributes).
