Introduced the parameterMemberMatcher,

a new constructor argument for CopyAndUpdateAssertion, allowing the parameter-to-member matching logic to be defined in a custom way.
Added a new 'copy and update' scenario,

which shows how to verify a 'copy and update' method which has parameter types that are different to (IsAssignableFrom in this case) the public property type.
Incremented minor version,

in order to indicate that the addition of a custom parameter matcher to
CopyAndUpdateAssertion is a new feature. This resolves #205
(https://github.com/AutoFixture/AutoFixture/issues/205).
