Title: Fix \stackrel argument order in MathML

The latex macro `\stackrel` shows the first argument above the second one, as a description. For instance

```latex
\stackrel{w}{\to}
```
should display as
```
w
→
```

However, the output was incorrect in MathML (since the order must be reversed: ` base overscript `). This patch fixes the order and adds a test.

Unfortunately, I cannot check the OMML output, so that one might still need patching.
