XAML Stripper

Here's my first attempt at a generic XAML markup stripper. It seems to work pretty well so far (test against CJ markup examples). It's not as efficient as it could be (I could be short-circuiting the main loop in more places, and maybe even handle entities in the first pass), but it should do if you don't have to convert a lot of items. I will see if I have time to optimize it, but if anyone wants to pick up the task, I won't complain

Some decisions had to made about whitespace handling - I decided to collapse them all just like Markup display does, but this may not be suitable for all purposes (e.g. matching against data from the source that you generated the markup from). I also decided to add space between plain text from different tags. This isn't always the desired result (for example, the baseline example has a a space between the word Baseline and the number 2 in the converted text, that doesn't appear on the markup display. But it is the preferable result in more cases so I went with it).
