Release 6.0.0-beta0002

Feature/redesign plumbing (#75)

The package had some large design changes that introduce breaking changes to the API if you were customising the model creation process. The following changes have been made.

- All ValueGenerator types have been moved into a ValueGenerators namespace.
- All TypeCreator types have been moved into a TypeCreators namespace.
- CreationRule has been replaced with ExpressionCreationRule, PredicateCreationRule and RegexCreationRule which are in the CreationRules namespace.
- The combination of build strategy, compiler and configuration have been replaced with just `IBuildConfiguration`.
- IBuildConfiguration is now mutable. A new IBuildConfiguration is created for each call to a static method on the `Model` class however that some configuration is used for the entire creation process. Any mutations to the build configuration will apply until the entire build tree has completed.
- `ICompilerModule` has been renamed to `IConfigurationModule` and now configures `IBuildConfiguration`.
- The `IgnoreRule` class has been replaced with the `IIgnoreRule` interface. The logic for processing rule matches moves from `DefaultPropertyResolver` to the rule itself.
- Renamed IValueGenerator.IsSupported to IsMatch
- Renamed IPostBuildAction.IsSupported to IsMatch
- Added IBuildConfiguration.TypeResolver
- Added IBuildConfiguration parameter to ITypeCreator.CanCreate
- ICreationRule, ITypeCreator, IValueGenerator, IPostBuildAction and IBuildLog now have overloads for ParameterInfo, PropertyInfo and Type rather than (Type, string)
- IExecuteOrderRule and IIgnoreRule now have overloads for PropertyInfo rather than (Type, string)
