Create the new python module to host the aforementioned code.

If present in the kamaki configuration file, the user will read

Before extracting an image or registring it with cyclades, the image
properties are populated with metadata concerning excluded deployment
tasks.

Inform the user about metadata changes performed during syspreps

Also fix various issues. snf-image-creator-dialog is almost ready.
Some `Help' entries are missing.

Also create a new output class (InfoBoxOutput) to be used when
performing syspreps

Populate Sysprep entry in "Image Customization Menu". Not fully
