[WIP] Updates for 0.4 Release

Incorporates GH-36 from @Gwayaboy.

todo:

- [x] Remove MVC dependency that was added to core code for html controls
- [x] Change ElementWithWait to Element and TryGetElement to OptionalElement (and ensure it has waitInSeconds parameter) (this would include the change in GH-38)
- [x] Ensure all waitInSeconds params default to 5 seconds
- [x] Change html controls to use autofac registration source and get rid of interfaces that are just for tagging to remove confusion
- [x] introduce a few methods / classes with [Obsolete] for until we hit 1.0
- [x] Document the breaking changes
- [x] Fix for GH-42
- [ ] Anything else we want for 0.4 from GH-41
- [x] Change wait parameters to timespans rather than ints
- [x] Add a configuration for specifying routes
- [x] Add ability to wait for the page title to become available

Let's try and make this the last HUGE release. Now we have CI we can hit the green button regularly for small changes and it doesn't become so painful to release!
