Add support for opening alien files directly from the command-line, like:

  alieve visscan_init.C'("alien:///alice/data/2009/LHC09c/and-so-on/")'

alieve_init.C
=============
- If path begins with 'alien:' and gGrid is not set, do TGrid::Connect("alien").

visscan_init.C
==============
- Add path argument and pass it to alieve_init().
