Add bottom left/right options for RenderPosition

This is in response to Issue #194. 

* I added new `RenderPosition` values: `BottomLeft` and `BottomRight` (kept the existing `Left` and `Right` the same - default is to Top, no reason to introduce legacy issues).
* Updated the css to adjust for these render positions when used with the profiler classes.
* Updated the include.js logic to account for bottom left/right positioning when showing the popup and queries.
* Added two new actions to Sample.MVC to demo/test bottom left and right. Uses the same logic from the Index Action, just sets the render position differently in the Layout file
