Changed logo sizes slightly to have better ratios

The old logo sizes were a bit odd, which made it really difficult to setup logos for our timber reports. Furthermore the "real" size on the reports was slightly different in each report.

This is now changed, so that we have a fixed ratio for the logos, which makes the logo creation easier.

The logos are always scaled proportionally, so the logos will still look good for existing customers. But they might recognize small size changes.
