The roundtrip of the math manual produces a compilable document now:

- translate the arguments of \texorpdfstring, so that the floating footnote
  code gets enabled
- honor the ForcePlainLayout flag of insets like the Index inset
- remove hardcoded \url support, this is handled by the general Flex inset code
