Disable garbage collection support.
Declare a dummy prototype for __dummyAction to quiet warnings from clang about undefined selector.
Quiet warnings about alpha constants passed to CGBitmapContextCreate. They are documented as being safe, so just cast them to quiet the warning.
scanHexInt takes an unsigned int pointer. Even though it's ignored, fix the typing to avoid a compiler error (and possible NULL reference?).
Declare a method prototype for a less formal delegate method that is relied upon by IMBNodeViewController. Quiets a warning about an unrecognized @selector.
Remove wiring to evidently obsolete showPopover: method. I believe whatever conveyance of information that was being achieved by this is now happening through other channels.
Update to recommended settings
ObjectiveFlickr: Remove garbage collection support
XPCKit: Update partly to recommended project settings

Excluded building for active architecture only
Another update to recommended project settings
Ensure atomicity of manual implementation of version property in IMBApertureParser

Parser will be used from different threads
Fix compiler warning regarding atomicity of plist property of IMBSafariParser

"Cannot pair synthesized setter with user defined getter".

Property must be atomic because IMBSafariParser will be accessed from different threads
Remove trivial user defined getter in favor of synthesized getter (will also fix compiler warning regarding atomic property)
Declare properties to be nonatomic if only one of getter/setter is synthesized and we are confident that objects with such properties will only be accessed from one thread
Merge branch 'refs/heads/master' into development
XPCKit: Add explicit reply dispatch queue to XPCConnection so that it is not primarily dependent on dispatch_get_current_queue()

This is a partial solution to issue iMediaSandboxing/XPCKit#1
Fix usage of dispatch_get_current_queue() (deprecated, fuzzy semantics when called from outside of a block) in favor of explicitly providing a return handler queue to SBPerformSelectorAsync()
Fix compiler warning regarding atomicity of property needsImageRepresentation of IMBObject
