Fixes #169: Security Issue in Parsing XML using NSXMLDocument

External entities are no longer parsed in appcasts: pre-10.7, we use the
"tidy" option for XML document parsing, which happens to behave this way,
and in 10.7+ we use a new explicit option for this behavior.

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.
Removing Japanese localization of the password prompt, since I changed the design
Allow the user to try reentering his password if authentication fails.
