Fixes #169: Security Issue in Parsing XML using NSXMLDocument

External entities are no longer parsed in appcasts: pre-10.7, we use the
"tidy" option for XML document parsing, which happens to behave this way,
and in 10.7+ we use a new explicit option for this behavior.

Use NSFileManager interface for DMG unarchive only for 10.7+. On 10.6,  [NSFileManager copyItemAtPath:toPath:error:] can fail with "Argument list too long" if the app bundle contains too many files.
The switch to NSFileManager was only required for 10.7 anyway, 10.6 always worked fine.
