noderunner: add support for alt dir and boot file

    This patch contains two additions to simplenode.runner:

1. Check if vm.args exists in CWD; if so, use it. This makes it
   easier to start multiple concurrent nodes on a single machine
   from one rebar-created release (starting each node from its
   own directory, with its own copy of vm.args and e.g.
   sys.config, log directory, database directory, etc.)

2. Add the targets start_boot <file> and console_boot <file>.
   This is used to select a different boot script. The 'setup'
   application (http://github.com/esl/setup) builds a special boot
   script for installation (all apps loaded but not started,
   making it possible to run install hooks with the full code path
   in place).
