Add EBox::Types::File

[ejhernandez@…]

New File type is created in order to do the following:

• In edition mode
  1. As editable: you can upload a file to overwrite uploaded content
  2. As non editable: you can see the file path if needed

• In viewer mode, the same as edition mode not editable. Additionaly, if you set an attribute, namely allowDownload may allow the user to perform the download of the selected file
