feat: release notes for 0.1.7; archive 0.1.7 iso; bump version to 0.1.8

Cut the 0.1.7 release (docs/tutorials, HTML man pages, updated man pages,
libc floating-point formatting, DOOM missing-WAD warning, ramdisk copy fix).
Archive the 0.1.7 ISO, publish it to the website, refresh release notes and
the downloads page, and open the 0.1.8 dev cycle (apiVersion 9, BuildNo reset).
