Allow disabling of confirmation page for paid events
Currently, a paid event must have a confirmation page. In simple paid event registration cases, it would be sometimes be preferable to skip the confirmation page (and potential drop-off of registrants or confusion from those who don't realize that the confirmation page wasn't the end of the process) and simply register the participant directly.
Note that you can skip the confirmation page on a contribution page and this is a very similar situation (people are making a selection and filling in their payment details). We find our supporters are likely to be confused by multiple, verbose pages and the confirmation page definitely adds complexity that isn't needed in some cases. Are there any downsides to giving users the option to set up events without a confirmation page?
