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).
Added Albedo to the list of dependencies in Ploeh.AutoFixture.Idioms nuspec.
Removed a test that no longer always passes.

This test must be a remnant of AutoFixture 2.x, because in that version
range, it was supposed to always pass. In AutoFixture 3.x, OTOH, it may
occasionally fail, which I've seen happen once. However, this only happens
rarely.
The test is incorrect for AutoFixture 3, so therefor I remove it. It's not
a breaking change, because the behaviour of AutoFixture doesn't change by
removing the test.
Incremented patch version,

in order to indicate that the addition of the Albedo dependency to the
AutoFixture.Idioms NuGet package resolves #208
(https://github.com/AutoFixture/AutoFixture/issues/208).
Added link to good article about contributing.
