Fixed: Remove explicit use of Mac OS X 10.5 SDK, replace with "latest OS X"

The fontinfo and imagesize Xcode projects still explicitly refer to using the Mac OS X 10.5 SDK, while all other Xcode projects simply refer to the latest Mac OS X SDK, with no explicit OS version. This change modifies these two projects to mirror other Xcode projects in the project.

FIXED: Crash due to tooltip trying to be attached to a window that is gone

Previously, _CPToolTip was not testing if the view and so parentWindow was still here. During the timer, it might be gone, which would cause crash. This patch ensure the window is still there before showing the tooltip

Tweak: use continuation lines so the tmLanguage symbol parser works correctly.
Fixed: oops, it should have been single backslashes.
Fixed: Variable scope in CPSegmentedControl.j
