0.7.0 Nuget Release

• New cache handle based on System.Web.Caching which can be used in ASP.NET 4 applications
  This cache handle relies on HttpContext.Current being available.
• New serialization interface
  Serialization can now be configured and extended. The default serializer uses binary serialization which is usually pretty slow and is not portable. Currently there is only one alternative with the CacheManager.Serialization.Json package. More to come soonish
• Simplification for configuration by code. Names for the cache instance and each handle are optional if applicable. The fluent builder methods have overloads without the names if possible. For some (redis) caches we still need the name to reference another configuration element though.
• Many small improvements and bug fixes
