- Fixed #1528, #1278, avoided ID's being cast to string for methods that return ID's as well as storePositions casting to string.

Provide the DataView.map() method similar to the DataSet one.

Added the following:
- dashes property to nodes in options.js
- dashes property with value false to defaultOptions in NodesHandler.js
- support for Arrays to selectiveNotDeepExtend function in util.js
- functionality to CircleImageBase.js that allows circularImage nodes to have dashed borders
- example demonstrating how to apply the dashed border to a circularImage node
- documentation explaining the usage of the dashes property on a node

- Dropped support for appending data returned by `DataSet.get()` to an existing Array or DataTable.
- Fixed a `window` issue in uuid.js.

- Added fontSizeMin, fontSizeMax, fontSizeMaxVisible, scaleFontWithValue, fontDrawThreshold to Nodes.
- Added fade in of labels (on nodes) near the fontDrawThreshold.
- Added nodes option to zoomExtent to zoom in on specific set of nodes.
- Added stabilizationIterationsDone event which fires at the end of the internal stabilization run. Does not imply that the network is stabilized.
- Added setFreezeSimulation method.
- Added clusterByZoom option and increaseClusterLevel and decreaseClusterLevel methods.

Still clustering bug and need more documentation on new features
