support for iCloud documents

This should add the features discussed in #1054.

QSDownloads is sort of a strange place for the new method, but I needed a central location and that seemed as good as any. Note that I didn't update objectHasChildren: as the test for it seemed too expensive.

Haven't tested this (not sure if I can?) but a quick question - I'm guessing the preset will show up for 10.6 and 10.7 users, anything we can do about that?

I had the same thought and meant to look into it before posting this. I thought there was a way to set requirements for presets, but I could be wrong.

OK, it should only show up in 10.8 now (or a possible future upgrade to 10.7).

Note: This will cause a merge conflict with #1055 as they both add new files to the Xcode project, but it's easy to resolve. There are two conflicts in Quicksilver.xcodeproj/project.pbxproj. For both of them, just accept the changes on both sides.

I want to work on that plist re-ordering pull request. Since this already has a merge conflict and that would make it worse, I'll just close this and rebase it after and resubmit.

Note that I reopened this as the conflict is in the Xcode project and is easily resolved as described above. :-)

Merged with @pjrobertson's blessing.
