Feature Request: Add archive load failure alert

[mikemcduffie]

Request that user notification be added when failing to load/process an archive. Currently SC silently fails to load a corrupt/mislabeled archive with no user feedback making it unclear what went wrong.

Likewise there is no notification when a corrupt image is loaded in an otherwise functioning archive. Typically a blank page is displayed even when the same image viewed in Preview or QuickLook shows the partial image. While less severe than the entire archive failure mode, it can be confusing as some comic archives actually contain blank pages by design (weird but true in my experience).

Both good ideas.
Honestly the archive handling is the most important, as it is indicative of a much more severe problem. Namely the Core Data infrastructure is fragile as all hell. Almost no fallbacks aside from the recursive delete if an archive goes missing.

I'm assuming you can get archive errors/warnings from XADMaster. FYI, XADMaster should be updated fairly soon for a bug in zip archive handling: https://bitbucket.org/WAHa_06x36/theunarchiver/issues/934/zip-archive-tests-extracts-with-7z-zip
