Update and fix VM Wizard text/functionality

VM Wizard header text now in its own template. Template is also used for the
final steps "finish button".

Includes a new django tag, which should be installed using pip. Necessary to
remove the newline inserted when including templates. Refer to this:
https://code.djangoproject.com/ticket/9198

Lined up check boxes, and separated that steps CSS into its own file.

checkbox will be according to your choice.
