* CA-297020: Do not download imported appliance on a modal dialog, but rather
asynchronously on the ImportSourcePage, so that the rest of XenCenter is usable
while the download is taking place; used the page's progress bar for this purpose
and removed the DownloadApplianceDialog.
* Corrections to the validation of the import source.

asynchronously on the SelectImportSourcePage, so that the rest of XenCenter
is usable while the unzip is taking place; for this purpose a progress bar
was added on the page and the DecompressApplianceDialog was removed.
