some bug fixes and stuff

Signed-off-by: somatonic <philipp@urlich.ch>

While working on a shop I made some small changes (text, and classes) and fixed the missing sc_phone field.

I also added a update script that checks for module version and the sc_phone field, if not found it will create and add it to the template.

I tried to do as much possible without changing modules but some things could be added to markup like id's or classes.
