Update to latest version of `Cake.Core` and `Cake.Powershell`

We recently updated to the latest version of Cake and now see some warnings produced by the script because the versions referenced in Cake.Services are outdated. Could you updated the project to reference the latest versions?

The assembly 'Cake.Powershell, Version=0.4.6.0, Culture=neutral, PublicKeyToken=null'
is referencing an older version of Cake.Core (0.29.0).
For best compatibility it should target Cake.Core version 0.33.0.
The assembly 'Cake.Services, Version=0.3.5.0, Culture=neutral, PublicKeyToken=null'
is referencing an older version of Cake.Core (0.29.0).
For best compatibility it should target Cake.Core version 0.33.0.
