Doesn't work when guest missing ruby

[Fuxy22]

If the guest is missing ruby like for instance on a laravel/homestead box the plugin does't attempt to install ruby or warn about it and instead it just fails to work.

Is this intended?

Ruby is required to be installed on the guest instance. You brought up a good point, the plugin should at least display a warning if Ruby is not installed. I'll leave this issue open until I add this feature.

This Ruby dependency on the guest instance kind of sucks in my opinion. A while ago I thought of possibly creating a universal notify-send binary port of notify-send.erb for vagrant-notify written in golang to eliminate this dependency problem, but I haven't had the time to learn the language.

vagrant-notify 0.5.4 or above will now display a warning message if Ruby is not installed on the guest.
