Fix Vagrantfile to develop Vagrant
Fix Vagrantfile to develop Vagrant

This fixes the following issues when using the provided Vagrantfile
that can be used to develop Vagrant.

* use -s for curl

* set a hostname

* set the config.ssh.shell in the development Vagrantfile

==> default: stdin: is not a tty

* export the DEBIAN_FRONTEND variable

==> default: dpkg-preconfigure: unable to re-open stdin: No such file or
directory

* import the mpapis public key to verify downloaded release

==> default: -su: rvm: command not found

* use official Ubuntu Trusty box

New release '14.04.2 LTS' available.
