* Fixed problems when installing onto non-empty target volumes. The

'system' folder will be a clean copy of the source volume. Other
  folders will be merged (as before), but in case a folder is in the
  way of a link or file from the source volume, it will now be purged.
* Clarified the alert for non-empty target volumes, so it is very clear
  what happens. (Maybe there ought to the be option to only copy the system
  folder, though.)
* Fixed a problem with copying attributes in certain cases.
* Fixed the main GUI not resetting state properly after encountering an
  error during the copy process.
