* The UI dialog is now in Qt. We run qrenderdoc.exe with a very minimal
startup to display the dialog and send the report.
* The flow has been simplified to have less text and an easier time to
just click through and send.
* On the first report, the user is gently nudged to enter their email
address for contact and by default the email is saved for next time.
They're not nagged more than once about this.
* Optionally the user can select to upload the capture. This is always
default off, and there is a confirmation dialog making sure the user
intended to select it.
* After the bug is reported, a unique URL is generated and returned
which the user can then click back on to see if there's any update. By
default the UI will also remember the URL and check it every couple
of days and alert the user in the help menu that there's an update.
