Semantic menus have wrong classes

[1jerry]

using example Invoices. Main menus are using Bootstrap classes. Attached is a diff file that fixes that.

@1jerry thanks for reporting, but this is not a bug.

Classes are hard-coded into input file, see here:

https://github.com/perak/kitchen-examples/blob/master/example-invoices/example-invoices.json#L198

https://github.com/perak/kitchen-examples/blob/master/example-invoices/example-invoices.json#L208

etc.

But, I agree that examples should not have any frontend framework specific classes.
