Estimating and recording VRBO fees automatically

(So I don't need to do it manually) it would be nice for OR (for each API-integrated VRBO booking) to automatically estimate and record host listing fee.

Notes:

- can be made optional

- VRBO pricing is pretty much the same for most -- if not, configuration option can be added to augment behavior of "VRBO estimator" for given user/property

- it would play nice with earlier "Net Earnings" request

- doesn't have to be ideal -- if it is off by $10 no one would care. If you want to be super-precise with it -- introduce "contingent" flag which would be set for entries that are estimated. If given value was produced as result of calc with contingent value involved -- such value should be displayed differently

While this isn't something that is fully automated because Vrbo has not made the transaction fees available through the API feeds, they don't need to be manually added to each booking either! 

Under the Tools > Import/Export page there is an option for Import Vrbo Commissions.

This page allows you to download your monthly commission report from your Vrbo Dashboard and import it, which will apply the host fee details to each booking in that report.

I used the tool -- it is neat. Would be nice though to:

- allow me to import multiple files at once

- decompress files automatically, so I don't need to do it manually for each file

- not to fail when importing zero commission for canceled booking

- have "estimated commission" entry in future bookings (replaced later by imported data)

:)

P.S. Also, I don't think OR handles guest fee on canceled API-integrated VRBO booking correctly -- it should be removed (or zeroed out) for fully refunded bookings, but it stays.
