Subject: Allow for a more flexible relup package location

Instead of forcing the user to put the tarball package
with the expected name (<relname>.tar.gz)and in the
expected location (releases/<version>) symlink this
fixed file name to a tarball existing in one of three different
places (releases/, releases/<version>,
releases/<version>/<relname>.tar.gz).
Refactor the install/upgrade escript to make it more
dynamic, it now runs commands that are passed from
the start script while accepting a variable number
of arguments.
Add a `versions` command to the extended start
script that prints out the currently installed versions
and their status.
