Save Html, Validating Hello<br/>World, Updated Example

I've added a couple of features and It's passing on Appveyor

1. Save Html - this saves the page source when called manually or from a test in error

2. Validating html that have <br/> tags in the middle of text
  * https://github.com/scottcowan/specbind/commit/2fc7ab9bb2dfe40b046883442a9a22664161abdb
3. Updated the example project to MVC4 so I didn't have to install it
  * https://github.com/scottcowan/specbind/commit/bd3bf12fedc6e320e5ca1878669014b9916f79a0
4. the rest is just house keeping

On a side, I noticed the date tests are dependent on having US date format, so they're all failing for me. 

That and I noticed WaitForPageActionFixture.TestExecuteWhenPageIsFoundAndUrlDoesntMatchAfterTimeoutReturnsFailure was failing on appveyor sometimes but It passed ok in the latest build

I haven't tested the codedUI side.
