* Orphan block files were wrongly reported if cutting or copying to
the clipboard then reopening the project in the same session.
* Fixed some crashes and incorrect movement of audio when dragging tracks.
* (Windows) Data loss is now prevented when encountering a corrupted
.aup file created in ANSI builds.
* (Linux) Restore building if USE_PORTMIXER is not defined.
