Update style/layout.
Fix grammatical issue reported by FichteFoll (thanks!).
Update reference to Ascension.

Now refers to Ascension 2.
Qualify the GLFW statement, add note about Ruby gems.
Link up glfw3 gem name.
Tweak wording; note use of C++11.

Figure it's important to mention that I use C++11, partly because it's
not C++98 and could be misleading, partly because I think that'll be
valuable to folks reading this.
Remove iOS stuff; haven't done that in years.

Add Scala alongside Java just because Ascension's written in Scala.
Remove iOS mention from MD as well.

I haven't done it in long enough that I'm not going to consider it a
thing I do right now.
Add specific project references.
s/recent/experimental/ and remove iOS. Add Rusalka.
Trim history entry.
Update README.
