Improve fallback values syntax with "Or"

[ChrisMissal]

Instead of using:

config.RetryAttempts(5);

for a fallback default, consider:

config.RetryAttemptsOr(5);

or

config.RetryAttempts.Or(5);

I'm not sure which I like more.

If you're trying to make it a "fluent interface" I'd prefer the last example. However, "Or" implies some type of conditional statement to invoke the "Or" path, like an out-of-range configuration value.

Personally I find the "Or" syntax vague for default or fallback values. Consider:

config.RetryAttempts.DefaultTo(5);

or

config.DefaultTo(5).RetryAttempts();

I'm a bit on the fence about this feature because you could simple do this as:

config.RetryAttempts ?? 5;

It's already built into the language so adding something like .DefaultsTo() would basically be that one line.
