Changes for Hype
Added an XPC service to deal with sandboxing.

This fixes #163. It requires that you copy the XPC service into your main application bundle in
Contents/XPCServices and runs the remove from quarantine step of copying the finish_installation
app as well as launching finish_installation app outside of the sandbox. Sparkle will function
exactly as it does now for applications that do not copy the XPC service into their application
bundle.

Fixes #44: maximumSystemVersion key
Removed methods from SUPasswordPrompt.h that didn't need to be exposed there
Redesigned password prompt UI
Removed changes to the project.pbxproj that were unrelated to the password prompt
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.
Delegated password prompting to the update driver.

The SUDiskImageUnarchiver shouldn't know about UI, and besides,
it's important that update drivers which should not display UI (like
the automatically-installing and probing drivers) should not display
password prompts.
