Timeout of 100 seconds when uploading a file

Created on behalf of #55 (comment)

I tested this release. It worked for the file in question. However, as I scaled up the file size I encountered Task timeout exceptions. There seems to be a 100 second task timeout. Maybe there is a config setting I'm missing?

	var upload = client.CreateUpload("...", "FTOS-SI-ON-9.14.2.8.bin");
	var bytes = File.ReadAllBytes(@"c:\temp\FTOS-SI-ON-9.14.2.8.bin");
	await upload.UploadDataAsync(bytes);

The default timeout for dotnet's HttpClient is 100 seconds. I'm currently working on creating examples to show how to do common things like setting timeout and proxy. They should be finished later today.

Turns out SimpleS3 didn't live up to its name when it came to retry and timeout logic. I've worked on it a bit and it should be a lot simpler now.

I've also added some new examples to show how easy it is. See here.
