multiple page numbering schemes. Numerous bug fixes and package
compatiblity fixes.

0.21.1
Bug-fix release.

Fixes:
- compress option
- \cpagerefrange with hyperref
- beamer "compatibility" (documents will compile; as was the case in all
previous cleveref versions, there's still no guarantee
everyting will work correctly with beamer)

Bug-fix release:

  - fix bug in \cpageref + hyperref

  - allow \crefalias'ing of appendix reference types

  - fix misleading \namecref undefined reference warning

  - make sub-reference types inherit from format components
    rather than low-level formats

  - fix spelling mistakes in Dutch translations
