Improve documentation (#730)

- Rework navigation among the multiple Doxygen projects for much easier use.
- Rename new ktx tool man pages from `ktxtools_*` to `ktx_*`
- Add `ktx` tool mainpage based on RELEASE_NOTES info.
- Make minor formatting fix in `ktx` man page.
- Update acknowledgements.
- Remove outdated TODO.md.
- Add script to do `$Date$` keyword smudging. Use it in CI and reference it from
  README.md to avoid repetition of list of files needing smudging.
- Add `$Date$` keywords to some docs.
- Remove `$Date$` and #ident keywords that are no longer needed or used.
- Document the parts of `khr_df.h` relevant to the libktx API.
