ESXi 5.0u2 template for VMware Fusion
Fix PATH issue in sudoers file for CentOS-5.5-x86_64-netboot

Added sed command to postinstall.sh to include PATH in the env_keep
block in /etc/sudoers. Makes it so vagrant is able to detect chef and
puppet on the VM.
Make the 'stdout/stderr/exit code' available during exceptions

An error is raised when a ssh_execute command returns an exit code is
greater than 0. This change allows use to capture that information in
a rescue call.

Example:
    ```
    begin
      # ... do something
    rescue Veewee::Provider::Core::Helper::SshResult => result
      puts result.stdout
    end
    ```
