SmalltalkHub upgrade!

Hi, I'm pleased to announce a new SmalltalkHub upgrade. This upgrade includes quite some bug fixes and speed improvements.

- new buttons to delete mcz files and packages - deleting projects will delete mcz files - team can now also be deleted - the MCZ cache is now correctly flushed when required - Private projects are now hidden from all public timelines - Speed improvements for some Mongo requests

Issue fixes:

- issue 16: Cannot delete project - Issue 1: Monticello Registration snippet should not supply user name - Issue 5: Some message should be shown when you try do delete the only member of a Team - Issue 6: I just got to see an Amber debugger while trying to log out - Issue 25: Remove packages does not work - Issue 23: Encoding problem

Cheers, Nico
