Critical fix for Radar chart, minor bugfixes and improvements

This is an intermediate release, with the following:

1. CRITICAL fix for Radar Chart, for a bug that caused an endless loop due to skipWebLineCount feature.
2. Custom minimum offset for Bar/Line/Pie charts
3. Support for legends above the chart
4. A new tvOS target
5. Other minor features
6. Other minor bugfixes and improvements

Swift 2.0, minor new features and bugfixes

• Moved to Swift-2.0 (Xcode 7)
• PieChart and HorizontalBarChart now support Markers
• Introducing FillFormatter for individual LineDataSets
• Introducing XAxisValueFormatter for custom XAxis label formatting
• General bugfixes and improvements

This release contains the binaries of 2.1.4a release, for Carthage users. This is to prevent the hanging Radar chart problem. Since Carthage does not support letters after version numbers, we can't rely on 2.1.4a for Carthage users.
