Back Unity Support 1.4.0

Notes

• Enable functionality in projects that reference Unity assemblies, not just those that have the VSTU project flavour GUID (#53)
• Improve handling of C# language version. Default is correctly set to C# 4, not 5. Uses C# 6 if option is enabled in Unity 5.5. Handles the CSharp60Support plugin. (#50, #60)
• Treat UnityEngine.Debug.Assert as assertion methods, so ReSharper includes asserts in control flow analysis. (#62, #63 - thanks @joshuaoconnor!)
• Add string formatting inspections for debug assertion messages.
• Renamed "message handlers" to "event functions", as per the Unity documentation.
• Display a "gutter" icon for implicitly used event functions and fields. (#58)
• Display colour highlights and the colour palette picker for UnityEngine.Color and UnityEngine.Color32. (#51)
• Fix MonoBehaviour.Invoke code completion and rename support in string literals to work with the correct class, not just the current class. (#66)
• Support undocumented messages, such as OnGeneratedCSProjectFiles. (#59)
• Fix namespace provider settings for Assets and Assets\Scripts folders. (#64)
• Sort event functions alphabetically by default in code completion.

From previous releases:
• ReSharper 2016.2 support. Thanks @cmcpasserby! (#44, #46)
• Added support for event functions for all Unity classes, not just MonoBehaviour. Thanks @swalex, @rorydriscoll! (#20, #29, #44)
• External annotations to improve ReSharper's analysis, e.g. implicit usage and nullability of Component.gameObject. Thanks @bigbadtrumpet! (#34, #13, #15, #23, #42, #43)
• Code completion, find usages and rename support for Invoke, InvokeRepeating and CancelInvoke (#41)
• Auto-suggest event function completion when creating methods
• Event function descriptions for methods and parameters displayed in tooltips and QuickDoc
• "Read more" in QuickDoc navigates to Unity API documentation
• Suppress naming consistency checks on event functions
• Add parameters to generated event functions (#8)
• Automatically sets Unity projects to C# 5. No more incompatible C# 6 suggestions! (#5)
