improvements from MapBox for 1.0.0 to latest

[incanus]

These are our latest improvements leading up to our 1.0.0 release back in the Spring and everything since then. Somewhat significant API changes, particularly ARC, but updating projects is pretty straightforward. As always, feel free to post any questions and we can go over things in detail.

• Automatic Reference Counting (ARC) support. (Use Automatic Reference Counting #78)
• Dropped iOS 4 support.
• Allow for library-wide custom User-Agent header for all network requests. (set specific user-agent for SDK requests mapbox/DEPRECATED-mapbox-ios-sdk#22)
• Updated SMCalloutView.
• Improvements to annotation selection. (Hiding of marker's bubble mapbox/DEPRECATED-mapbox-ios-sdk#189)
• Allow selection of nil annotation to deselect.
• Updated project for Xcode 4.6.
• Various documentation improvements.
• Fail map view init when passed an invalid tile source.
• Renamed long-press map gesture for consistency with Apple.
• Added long-press annotation gesture. (use long press for annotations drags mapbox/DEPRECATED-mapbox-ios-sdk#181)
• Renamed some properties to be more intuitive to use and easier to autocomplete (draggingEnabled, bouncingEnabled, clusteringEnabled).
• Don't change map center if value passed isn't different. (re-center on existing center has delegate issues mapbox/DEPRECATED-mapbox-ios-sdk#186)
• Silence some iOS 6 deprecations since iOS 5 is still supported. (fix some iOS 6-only deprecations mapbox/DEPRECATED-mapbox-ios-sdk#179)
• Adjust user heading path width based on accuracy. (update heading path width based on accuracy mapbox/DEPRECATED-mapbox-ios-sdk#75)
• Annotation layers shouldn't be draggable by default.
• Clustering improvements to make API simpler (isClusterAnnotation, clusteredAnnotations).
• Don't begin tap gesture zooms in/out if already at max/min zoom. (re-center on existing center has delegate issues mapbox/DEPRECATED-mapbox-ios-sdk#186)
• Annotation layer hit test cleanups. (Fatal memory leaks for clustered marker annotations mapbox/DEPRECATED-mapbox-ios-sdk#171)
• Properly notify map delegate of callout auto-moves ending.
• No longer allow callouts on cluster annotations. (Fatal memory leaks for clustered marker annotations mapbox/DEPRECATED-mapbox-ios-sdk#171)
• Cleaner API for move/zoom delegate notification commits.
• Properly sort circles with other shapes in z-ordering.
• Removed slight delay when displaying callouts.
• Fix shape/circle hit detection passed on presence of fill color.
• Public/private header cleanup. The idea here is to make private any headers that a normal user of the library would not use, such as RMMapTiledLayerView.h.
• Added fillPatternImage to RMShape and RMCircle.
• Projected point equality test bug fix.
• User location accuracy circle now bounces on first location update. (make accuracy circle bounce mapbox/DEPRECATED-mapbox-ios-sdk#27)
• Removed boundingMask & made minZoom automatic per passed frame. (simplify bounding mask mapbox/DEPRECATED-mapbox-ios-sdk#12)
• Readjust loading tile background after map frame changes. (zoom background not visible at first mapbox/DEPRECATED-mapbox-ios-sdk#156)
