ODB++ post-merge issues

Description

• File name of compressed output can't be controlled (is always just odb.zip
• When creating compressed output, the uncompressed output is left in place also
• The progress dialog just shows one phase the whole time ("Init Entity Data") and this description is not a good user-facing string (it sounds like programmer speak)
• Assembly data is reported to have duplicate designators by Aisler
• Component mount type (SMD/THT) is reported missing by Aisler
• Exporting ODB++ marks the board as modified (* shows up in PCB editor title bar)
• Issues with bezier curves -- see test board from #9764 and screenshot posted as comment.
