Fixes #18 by wrapping the shell script in an osascript with administrator privileges. When running install or uninstall, this now pops up a dialog where credentials can be given. When running from a normal user account, one can enter both name and password of an administrator to get the resolver links in place.
Use the platform abstraction already present in Vagrant
Passing the plugin command line options to the DNS daemon as run options seems to segfault my Vagrant ruby. Only passing ARGV for start/stop seems to fix this.
Using the osascript, rvmsudo is no longer needed.
