Fix launch crash from zombie delegate

1. VBXFolderListController would indirectly
   release itself in a delegate callback when
   there were no other strong references
   remaining, causing the rest of the method to
   call the now-zombie self.

   Fixed by a [self retain] inside the method.
   The [self release] at the end will release
   the last strong reference and nil delegates via
   -dealloc to prevent any more calls, as usual.

2. UIKit still has an assign reference to the
   controller via the table view's delegate and
   dataSource. After fixing (1) above, this causes
   another crash.

   Fixed by nil'ing the table view delegate and
   dataSource in -[VBXTableViewController dealloc].
Fix disappearing "empty table" message

The superview of the table view in iOS 7 is
occasionally missing or transient.
-[self retain] before another delay cancellation

Just in case.
Fix assorted memory management issues

(as reported by clang)
Replace pool macro with @autoreleasepool
Add missing import
Replace VBXResourceLoader's target/sel with blocks

Because the variadic NSInvocation selector
dispatch was too type-unsafe, and interacted
badly with ARC.
