NUnit.Retries

Couple of helpful attributes for test retries:

• RetryOnErrorAttribute is like NUnit's own RetryAttribute, but it can be applied to whole Fixture/Suite/Assembly, and supports retry after exceptions in test, not only assertion failures
• On top of that, RetryOnTeamCityAttribute also supports TeamCity's test retry feature
• NoRetryAttribute for disabling retries

Attributes can be overriden on any level, e.g.

• MyAssembly.dll: [RetryOnError(2)]
• MySuite.cs: [NoRetry]
• MyTestFixture.cs: [RetryOnTeamCity(3)]
• MyTestMethod(): [RetryOnError(4)]

This means we have two retries on assembly level in MyAssembly.dll, but no retries in MySuite, if MyTestFixture is also in MySuite, previous attributes are overriden by RetryOnTeamCity, and method MyTestMethod in MyTestFixture is retried 4 times.
