Bug 10762: (follow-up) Update test plan, add kohastructure.sql files

I also change the default value for scale_height to '0.01'

Test plan:

1)Home > Cataloguing > Tools: Label creator > Manage Layout or New Layout
2)Make a new layout or edit an existing one
3)Notice the 2 new fields "Barcode width/Barcode height"
4)Save it like this
5)Create a batch of barcode and export if in PDF
6)Notice the size of barcode
7)Go back to your existing layout
8)Enter some values (Barcode width: 1.6 / Barcode height: 0.02), save
9)Take back your batch of barcode and export it in PDF
10)The barcode should be 2x bigger
